content: Thermal Master THOR-002 Handheld Thermal Imaging CameraReviewBy FraserFull disclosure:I was approached by Thermal Master and asked whether I would be interested in testing their THOR series thermal camera that is due for release soon. I agreed to test a pre-release sample camera if I could also write a review of it for the EEVBlog thermal imaging forum. Thermal Master agreed and sent me a THOR-002 camera to test. What follows is my honest and unbiased review of this new camera. I do not work for Thermal Master and will not receive payment for this review.IntroductionThermal Master are about to release their first "Pistol Grip" format complete thermal imaging system and asked if I would test it with a view to providing feedback on the design and performance of the unit. I am always happy to test thermal cameras so it was an easy decision. I have been testing the camera since it arrived in April 2025. The testing has been based on what I would expect a general user to do with the camera, rather than a specialist role. That said I will be including an annex on the THOR-002 in a PCB inspection role as I know many readers will be interested in that usage scenario.Unboxing:The Thermal Master THOR-002 is supplied in a hard case type storage container that has a custom foam insert to hold the camera securely during transport. The foam insert has storage holes for the USB cable and a close-up lens that is not supplied with the THOR-002 model.In the case there is the THOR-002 camera, a USB A to USB Type-C cable, a calibration certificate and a Quick Start guide.The hard case is relatively light weight so as not to add too much weight to the camera when carrying it around. Some users may elect to buy a suitable soft pouch type case to protect their camera when working on site.I attach the Thermal Master THOR-002 brochure and User Manual pdf's below

content: Description of the THOR-002Upon unpacking the THOR-002 I was immediately aware of how similar it looked to the FLIR Ex series, but with a slightly larger head. Thermal Master intend for the THOR series to compete in the marketplace against the FLIR Ex Pro series so a very similar styling is not unusual or unwelcome. The "pistol grip" format with thumb operation of a keyboard is a very ergonomic case format. In my experience, far more so than operating a mobile phone with a USB dongle hanging out of the USB port, but that is personal preference.When I hold the THOR-002 it has a very solid and well built feel to it with no obvious flex in the plastic casing and it has a good weight to it without being unpleasant to use. The whole camera oozes quality and if it had a FLIR brand label on it, I would not have questioned its origins. As a firm fan of FLIR professional thermal imaging cameras this is no throw away comment from me. Before I even switched on the THOR-002, I could see that a lot of effort had gone into its design and I was hopeful that its performance would be equally impressive. I also like the fact that Thermal Master have not used lots of shiny trim on the casing that can, IMHO, "cheapen" the look of a professional use camera. The sides of the camera head have quality trim in the form of a 3D Aluminium Thermal Master Logo trim plate and a thick acrylic trim plate on the other side that contains an ID plate within it. Beautifully executed in both cases.Thermal Master have employed two optical protection systems for the thermal imaging lens. The first is a thermally transparent window in the cameras casing that prevents dirt and moisture ingress. In front of that window there is a red plastic lens protection cover that may be swung into place in the same way as that found on FLIR Ex series cameras. This dual layer of protection is excellent and means that accidentally forgetting to close the lens cover does not expose the fragile thermal imaging core lens to harm or dirt. The cameras case employs a gasket around its edge seam to prevent fluid and dust ingress whilst working in hostile environments.The handle of the THOR-002 is well contoured for a firm grip and the index finger falls naturally onto the grey trigger, ready to capture images. At the base of the handle we find a very nicely made satin finish aluminium plate that contains both a 1/4" 20tpi tripod socket and a safety lanyard attachment point.Moving to the head section of the THOR series camera, we find a recessed port bay that is well sealed with a rubber cover/insert. Behind the cover there is the Type-C format USB charging and communications port and the MicroSD card in its socket. Thermal Master include a 32GB MicroSD card with the camera and this is pre-installed for the user. The form and fit of the rubber cover/insert is very good with no problems with it coming out during use.The rear face of the cameras head provides the user with the display and keyboard. The display is a quality 640 x 480 pixel IPS type and this is a welcome sight on a thermal imaging camera. The displayed image is bright and crisp. This use of a quality IPS display should not be understated as it is a great improvement over standard LCD panels. The IPS display is not touch sensitive, but touch screens can be more trouble than they are worth and can also reduce image clarity. At no point during the testing did I miss a touch screen as all functions are easily accessed "single handed" with just the thumb and keypad. Whilst some thermal cameras may have a good case for inclusion of a touch screen, I do not need one when using the THOR-002. I was impressed to see that Thermal Master have fitted a proper screen protector film to the IPS display to protect it from scratches during use. I wish more manufacturers would do this. The keypad comprises 4 discrete push buttons and a 4 way "Navipad" that contains a centre button. Whilst the tasteful grey keypad buttons might be mistaken for the "Rubber membrane" type, they are in fact a quality rubber button mat operating on real tactile push buttons that provide a satisfying 'click' when pressed. This is further evidence of a quality design.Associated with the keyboard for operation of the camera, is the trigger at the top front of the handle. Once again, we find a tasteful grey coloured trigger made from good quality hard plastic in a satin finish. The satin finish is a small thing, but again, it shows restraint and quality design. It would be so easy to provide a cheap looking gloss plastic trigger. When the trigger is pulled, there is a surprising, but not unpleasant, feel to it. The trigger is acting on a tactile mechanical switch via a rubber sealing membrane and this creates a 'soft' feel to the trigger movement as it is pulled and then the tactile switch is felt and activated. The rubber membrane provides sealing of the trigger aperture and is an essential component in an industrial grade camera.The front face of the THOR-002 is home to sealed apertures for the Thermal imaging camera, Visible light camera, Laser pointer and torch LED. The front face is recessed in the 'rubber' surround to help protect it from bumps and the lens shutter lever presents itself to the user below the front panel 'chin', just above the trigger. The thermal lens cover is the only item on the camera to be brightly coloured and is red hard plastic so may be clearly seen when closed.Operation of the THOR-002 is very simple and well thought out. I did not need the user manual to operate this camera 'straight out of the box'. That said, I did read the manual later, as I encourage all owners of such equipment to do. It is easy to miss functions or misunderstand them otherwise.The keyboard provides the following keys/buttons for control of the camera.1. Power Button - long press to switch the camera on or off and short press to place the camera in standby ready for a fast start with another short press.2. Play Button - this provides access to the saved picture and video gallery3. Torch Button - this button is dual function. A short press switches the torch on or off and a long press switches the laser on or off. Both laser and torch may be activated at the same time using the combination of a short press and a long press of the button.4. Back Button - the 'back' button is dual function. Whilst in menus, it acts as a 'back' or exit button. Whilst the camera is operating in its normal observation mode, the 'back' button may be used to activate the FFC event whenever it is pressed. This can be useful when taking temperature measurements to ensure best accuracy which is normally immediately after an FFC event.5. The Navipad - Navipads are quite a common and convenient menu navigation user input device and such is the case with the THOR-002. Its positioning on the camera makes it easily accessible using just the users thumb and permits single handed operation of the camera for both imaging and configuration.The "Navipad" comprises four 'direction' buttons and a centre button acting as a 'select' or 'enter' key. To access the cameras user menu the centre button is pressed and a row or 4 icons appear at the bottom of the screen. these icons and associated menus are navigated using the "Navipad" direction and centre select/enter buttons.

content: Battery and ChargingThe THOR series use a built-in Li-Ion battery that is charged via the USB-C style socket mounted on the top of the camera The battery run time is stated as 8 hours continuous use with a recharging time of 4 hours. The THOR-002 camera is supplied with a USB A to USB Type C cable for the purposes of charging and data connection to a PC. The USB charger is not included in the kit and must be supplied by the user. I will not criticise Thermal Master for not including the USB charger as this is a World wide initiative to reduce eWaste as people often already own several such chargers for other devices, such as mobile phones. I purchased a good quality USB charger for £9 what will stay with the THOR-002 in its case.Data connectionThe THOR series may be connected to a PC for UVC streaming or the downloading of saved images and videos. The saved images, once downloaded to the PC may be analyzed using the Thermal Master "Thermal Smart” Windows software that is available for download at no cost to the user.The THOR series cameras may also operate as a Wi-Fi Hot Spot in order for a mobile phone to access the live and stored imagery on the camera. Configuring the camera as a Hot Spot is a simple operation and Thermal Master provide the Thermal Smart Mobile Phone App required for the data link. Both Android and iOS are supported.The Thermal Master Download area for obtaining the PC software and Mobile Phone Apps is to be found here:https://thermalmaster.com/pages/download-centerI have also uploaded the 2D bar code for obtaining the Mobile Phone Apps.

I have plagiarised parts of Thermal Masters response to my question in the text below."X3""X3" is an AI algorithm driven resolution enhancement technology that produces a 512 x 384 pixel image from the original 256x192 pixel raw image data in real time without impacting frame rate. Whilst it is a "Super Resolution" technology, it does not require movement of the camera to create the resolution enhancement."Razor X"At the heart of the THOR-002 camera is the powerful Razor X image processing engine. This uses AI deep learning to intelligently suppress noise and interference within the image. Razor X analyzes each captured frame in real-time, adapting the optimal algorithm based on different scenarios to enhance the dynamic range of the image. This not only makes the image clearer and sharper but also highlights the targets more prominently."IQ+"IQ+'s powerful portfolio of algorithms includes a dynamic temperature compensation algorithm that detects ambient temperature in an intelligent way. It automatically compensates in real time using a complete mathematical model of atmospheric conditions. From this I believe IQ+ enhances measurement accuracy.

content: Operation of the camera menus.....To enter the cameras menu system, the user presses the centre button of the "Navipad" and this will bring up a row of 4 menu icons at the bottom of the display. From left to right these are "Measurement", "Image Mode", "Palette" and "Settings". The required icon is highlighted using the left and right "Navipad" buttons and selected with a press of the "Navipad" centre button.Measurement MenuOnce selected, the measurement menu brings up a row of 9 icons at the bottom of the screen. These are, from left to right, "Centre Spot", "Max.", "Min", "Custom Spot 1", "Custom Spot 2", "Custom spot 3", "Temperature difference addition", "Temperature difference removal" and "Delete all"Function descriptions"Centre Spot"is the spot temperature measurement point that is positioned in the centre of the display to measure the temperature of a target by aiming the camera. On the THOR series this centre spot is shown as a solid spot surrounded by a circle. I find the spot marker design a little obtrusive in images but can live with it. There is the option to switch on the centre spot measurement by pressing the "Navipad" centre button. It is a toggle function so one press to add the centre spot measurement and one press to disable it. The measured temperature appears at the top centre of the display in a large font for ease of reading. The temperature unit may be set in the setup menu."Max."is the "Hot Spot" tracking marker that dynamically finds, marks, and measures the hottest part of the thermal scene. This is very convenient when investigating a scene and wishing to see the hottest part of it without having to use manual markers or assessing the scene by eye. Just as with the "Centre spot" function, the "Max." measurement is activated and deactivated by selecting its icon and pressing the "Navipad" centre button. The "Max:" temperature measurement is displayed at the top left corner of the display and is of a good font size for ease of reading. A Red crosshair is positioned over the point at which the "Max." measurement was made so that the User can easily identify the thermal source location in the scene."Min" is the coldest spot tracking marker function that dynamically locates the coldest point in a thermal scene before marking it and providing the user with a measurement. It is activated and deactivated in the same way as the other measurement functions, using the "Navipad". The coldest point in a scene is marked with a green cross hair. Whilst a blue cross might seem logical, it can cause visibility issues if used on a colour palette where cold areas are shown as blue."Custom Spot"1, 2 and 3 - These are measurements points that the user may activate and move around the displayed scene using the "Navipad". This is a useful function when a user wishes to monitor the temperature of up to three specific targets within a thermal scene, rather than just the "hottest" or "coldest" point. Such a measurement function is often used during Electronics PCB analysis to monitor multiple component temperatures simultaneously. The custom measurement point is activated by highlighting its icon and pressing the "Navipad" centre button. A measurement point cross appears on the display. The cross is then moved around the display using the four "Navipad" direction buttons. Another press of the "Navipad" centre button fixes the measurement point location and a P1, P2 or P3 and measured temperature appears next to it in an easily readable font. The custom measurement point may be deleted by selecting its icon on the menu and pressing the "Navipad" centre button. All custom measurements points may be deleted at once using the "Delete all" icon on the measurement menu."Temperature Difference addition"provides the user with the ability to determine the difference in temperature between any user set measurement point and one of the following:"Min"(the minimum temperature in the scene)"Cen"(the temperature at the central measurement point)"Max"(the maximum temperature in the scene)"Custom"(a temperature value set by the user)There is no option to measure the differential temperature between two user set measurement points.The mathematical function is (Temperature Point Px) Minus (Selected Min/Cen/Max/Custom value) = Differential temperature.Each of the three user set measurement points may have a differential calculation associated with it.The result of the differential calculation is displayed on the left of the cameras display."Temperature Difference removal"is used to delete any, or all of the differential temperature calculations."Delete all"is used to remove all custom measurement points and temperature difference measurements from the display. The deletion is activated with a press of the "Navipad" enter button and a confirmation challenge appears on screen to check that it is an intended action. Only the custom measurement points and temperature difference measurements are deleted. If "Centre Spot", "Max." and "Min." are activated, they continue to be active until disabled in the measurement menu by the user.To exit the measurement menu the user must press the "Back" button and this reverts to the main menu of 4 icons. The "Back button is pressed again to return to scene observation mode. Note that images cannot be saved whilst the menu is visible on the display. The user must completely exit the menu mode."Image Mode"Once selected, "Image mode" presents the user with 5 icons along the bottom of the display. These are, "IR", "Visual", "Fusion", "PIP" and "Fusion Alignment". The functions of these modes are as follows:"IR"provides a displayed image that is purely in the thermal domain with no input from the cameras visible light camera."Visual"provides a displayed image that is purely in the visible light domain with no input from the cameras thermal imaging module. Basically a digital camera mode."Fusion"is sometimes known as "Thermal Overlay" mode where a Visible light image has the thermal scene overlaid on it to provide context to the thermal image with respect to the content of the scene. Whist this mode can be useful, with the THOR cameras 256 x 192 pixel resolution it is by no means essential for an understanding of the detailed thermal scene that the camera is presenting to the user. A very useful feature of the "Fusion" mode is the ability to capture details such as labelling that would not be visible in the thermal domain alone. When viewing an electrical fuse or breaker board, the circuit allocation labelling may be seen as well as any thermal issues that are present. Such may then be saved to the cameras memory if desired. Once "Fusion" is selected, the camera presents the combined/fused thermal and visible light images to the user and the amount of thermal image visibility on the visible light image may be adjusted between 0% and 100% using the left and right buttons on the "Navipad". This ensures that the thermal image does not obscure desired detail in the visible light image and is sometimes called the "transparency" setting. Fusion mode may be disabled by going back to the "Image Mode" menu and selecting another image mode."PIP"is short for "picture in picture" and provides the user with a visible light image of the scene that has a central area of the display showing the thermal image of that same scene. This is used to provide the user with better scene awareness whilst being able to also see the scene in the fully thermal domain. As the camera is moved the targets transition smoothly from the visible light area into the thermal imaging region at the centre of the display. The size and position of the thermal image "window" is fixed but Thermal Master have chosen a sensible size that will suit most users needs. The thermal window is positioned at the centre of the display and is of 50% display width and 50% display height."Fusion Alignment"is a utility function that is used to align the visible light and thermal images when using the "Fusion" mode. Whist the two camera systems fields of view may be closely matched in hardware, there will always be parallax error when trying to overlay one cameras images over the others as the lenses have 15mm of vertical separation. To compensate for this parallax error the user is provided with the ability to fine tune the vertical and horizontal image alignment using the "Fusion alignment" menu. Once selected, this menu brings up an image of a "Navipad" on the display and the cameras physical "Navipad" is then used to align the visible light and thermal domain images at the desired distance from the target. Parallax error correction needs to be adjusted for different working distances from the target so is not really a set and forget" configuration function. It is needed during use of the camera in image Fusion mode, hence its presence in this menu set."Palette"is found on most modern thermal imaging cameras and is used to provide the user with a 'false colour' overlay of the thermal scene in order to assist in identifying regions of differing temperature. Some colour overlays are quite reserved in nature whilst others are harsh and intended to provide high contrast imagery for ease of interpretation. The most basic thermal image of a scene is often presented to the user in monochrome where the coolest areas are black and hottest are bright white. The temperatures between these extremes are gray scale. Some users prefer an inverse of this and have the hottest areas shown as Black and the coldest areas as white. This is sometimes a better option when carrying out wildlife observation. The monochrome display modes are very clear and a Thermographer can easily interpret the scene. Colour Palette overlays have become popular and most modern thermal cameras offer a few colour palette options. Such is the case with the THOR camera series. Selecting the "Palette" icon brings up 7 palettes for the user to choose from. These are: "White Hot", "Black Hot", "Lava", "Iron", "Rainbow", "Rainbow HC" and "RdGy" (red to grey). The desired palette is selected by highlighting its icon and selecting it with the "Navipad" centre button."Settings"is the menu that contains the configuration menus for the camera along with user preferences. Selecting the "Settings" icon brings up a list of menus that may be used to configure the camera. These menus are:"Measurement Parameters""Temperature measurement range""Alarm settings""Capture settings""Isotherm""Super-resolution""Video settings""Index mode""Unit settings""Wi-Fi settings""Screen display""Auto power off""System settings""Measurement parameters"contains the settings for Emissivity, Atmospheric Temperature and Distance to target."Temperature measurement range"provides the option to select the -20~120 Celsius range, 100~550 Celsius range or "Auto mode" where the camera automatically selects the most appropriate range itself."Alarm settings"provides the user with options for setting temperature alarms associated with Max., Centre Spot and Min. spot temperatures. There is also the option to automatically capture images upon an alarm event. The interval between, and number of, captures is configurable."Capture settings"provides options for "Auto save" of an image without a preview when the camera trigger is activated. There is also a "Time lapse capture" option that permits the user to set an automatic image capture process that has a user settable interval and the number of captures."Isotherm"provides options to set the "Above", "Below" thresholds or "within Low & High" thresholds."Super Resolution"is the X3 mode that Thermal Master uses to enhance the resolution of the cameras produced image using "AI". The mode is switched on and off using this entry."Video settings"permits the user to configure the auto-saving of video without preview after completion of a MP4 video recording. There is also an option for "Silent recording" that disables the cameras internal microphone."Index mode"is a function that changes the saved image 'Date-Time' titles to a simple incremental numeric format."Unit settings"offers the user a choice of both temperature and distance units."Wi-Fi Settings"provides control over whether the cameras built-in Wi-Fi Hot Spot is active, or not. It also provides the cameras Network name and Password. There is no option to select the 2.4GHz or 5Ghz band and the Hot Spot appears to be 5GHz only."Screen Display"offers the user a list of items that will appear on the user display whist the camera is in use. This permits the user to have as much, or as little data overlay visible as they desire. It is possible to turn off all overlays on the display if desired. The list is as follows:"Temperature Scale" (colour palette bar and temperature scale)"Hotspot" (Wi-Fi 5GHz Hotspot)"Memory Card""Time" (Time and Date displayed)"Emissivity""Enlarge" (Digital zoom level)"Temp Unit" (set temperature unit at the top of the display)Note that whatever is selected to be visible on the users display is also recorded on the Radiometric JPEG saved image, basically like a screen capture. The radiometric image is also available via the Thermal Master provided PC software and this does not contain the data overlay, but it is not an X3 resolution enhanced image (It is 256x192 pixels radiometric)."Auto power off"provides 5 auto power off options. These are: "off", 5, 10, 20 or 120 minutes."System settings"is a menu offering the user camera setting options. These are:"Device information""Restore factory settings""Format SD card""Brightness" (display)"Date & Time""Language options""Update" (firmware)"Open Source licence"Of interest is the last entry"Open Source licence". This contains a whole list of Open source code attributions and it is a comprehensive list. This is good to see.

content: Firmware Update to Version 1.2.0 June 2025At my request, Thermal Master added a manual Level and Span mode to the THOR camera series. The function works in much the same way as that found on the FLIR Exx series. The Temperature bar on the right hand side of the image has an upper and lower temperature limit shown. In manual mode, the upper, lower or both temperature limits may be adjusted by the user to meet the needs of a specific situation.The installation of the firmware update requires that a update file is loaded onto the cameras microSD card and the update option selected in the setup menu. The update process proceeded without incident but it is essential to select "Factory Reset" in the setup menu in order to complete the Firmware update. failure to do so results in the manual mode being selectable but it is not functional.The manual mode is available in 256x192 pixel display mode only so the X3 AI resolution and image enhancement mode needs to be switched off. The camera helpfully warns the user of this fact when Manual mode is selected with X3 mode still on.The update has created an additional menu entry for the Manual Level and Span function. This function may be switched on and off and when on, the Auto/Manual mode is selected using the "Play" button on the keypad. Once in the manual mode, the "Navipad" is used to select the temperature to be changed (Upper/Lower/Both) and, after selection, adjust the value(s). The addition of this useful functionality is welcome and I remain impressed at the response of Thermal Master to my request for its inclusion in a firmware update.Posts: 14106Country: gbView Profile Personal Message (Online)Important update 23 July 25….Just a small comment regarding the Firmware V1.21 that I am testing. This firmware provides the manual level and span mode for the THOR-001 camera but it does not provide that feature on the THOR-002. I have queried this with TM and will confirm whether the THOR-002 will have the manual level and span feature.Update 24 July 25….It is confirmed. Only the THOR-001 will off the manual level and span mode.

content: The user experienceThe THOR-002 was a joy to use and it felt very much like the "pistol grip" format FLIR thermal cameras that I am very used to. The camera is easy to control using the ergonomic keyboard and menus. I felt at home with the user interface as soon as I began using the camera.The camera feels comfortable and solid in the hand, in fact it really should be called "Mjollnir" as that was THOR's hammer and this Thermal Master camera feels like you could drive nails with its solid head and excellent build quality.Not that I am suggesting or condoning abuse of thermal cameras of course !I have absolutely no complaints about this cameras design and build quality. Both are excellent.In terms of the imaging performance of the THOR-002 I entered the testing phase with an open mind. The THOR-002 looked the part, but can it deliver the goods on the imagery that it produces ? Before we dig deeper into that topic, we should first consider the design of the THOR-002 thermal image capturing system. The physical microbolometer resolution is 256 x 192 12um pixels so this will always be the physical constraint within which it must work. The microbolometer pixels are only 12um in size so can be quite noisy but Thermal Master are using VOx coated pixels that provide an excellent signal to noise ratio that normally outperforms A-Si technology pixels, though A-Si has improved over the years. The combination of VOx pixels and decent image processing results in a very good thermal image at 256 x 192 pixels without the Thermal Master X3 resolution enhancement active. There is plenty of thermal sensitivity and I have no complaints about the THOR-002 microbolometer performance. It is typical of the modern 256 x 192 pixel microbolometer cores coming out of the likes of IRAY and Guide Sensmart these days. Would higher resolution be better ? Of course it would, but then costs would increase. Thermal Master decided to invest in an AI driven resolution enhancement mode that they call "X3". I am not privy to the exact nature of this resolution enhancement process but the visible effect on the displayed images is impressive. The X3 mode is also referred to by Thermal Master as "Super Resolution" but this is not to be confused with the Super Resolution modes that use hand shake and image stacking to increase image resolution. X3 uses AI algorithms and does not use hand shake movement or image stacking. This means that the frame rate is not impacted by the resolution enhancement process. Now it would be foolish to think that an AI algorithm can effectively convert a 256 x 192 pixel microbolometer output into a 512 x 384 pixel format identical to a physical 512 x 384 pixel microbolometer, but X3 does a fine job of greatly improving the appearance of the images presented on the display of the THOR-002. X3 is not perfect and can be confused a little by very low contrast scenes, but this is understandable and did not cause me any issues. The user has full control over whether the X3 resolution enhancement mode is active or not so can choose to use the camera without the AI algorithms involvement. It should also be stated that the X3 mode enhances more than just the presented resolution of the captured image. The whole image gets processed to increase contrast and reduce image noise. It can be a very impressive mode that I found a pleasure to use and useful. Note that the saved Radiometric data in the JPEG file remains 256 x 192 pixel values with no X3 enhancement present. This provides the purest data for analysis in the PC based Thermal Image Analysis software. Did l like the imagery that the THOR-002 captured and displayed on its crisp IPS display ? Yes, I did, very much so.Now, no product is perfect and I quickly identified something that was sadly missing from the THOR-002 and it is something I consider essential to a professional thermal camera. I am talking about the ability to select a manual Level and Span mode that gives control of Level and Span to the user rather than the AUTO mode that dynamically changes Level and Span to suit the full temperature range present in the thermal scene. I discussed the absence of a manual Level and Span mode with Thermal Master and described why it is needed. I was impressed with their prompt and positive response to my suggestion. Thermal Master really want this THOR series of cameras to shine in the marketplace so they listen to feedback from end users. They provided me with Firmware 1.2.0 in June and this includes the manual Level and Span function that I requested. The firmware was installed without difficulty and the new functionality works as it should, just like on my FLIR E40.I attach some of the Thermal Master advertising images for information.

content: Camera testingThe THOR-002 camera is designed to be a general use thermal imaging camera, much like the FLIR Ex and Exx series cameras. It uses a fixed focus lens with a focus range of 30cm to Infinity so it mirrors the minimum focus distance of the FLIR Ex series. This needs to be considered when testing this camera. It would not be sensible to expect this camera to provide amazing imagery of tiny SMT components on a modern high density PCB from a distance of 30cm. The camera may show "hot spots" but not fine detail. This is not a criticism of the camera, just a fact of physics, resolution minimum working distance and IFOV. As many will know FLIR Ex series users made their own supplemental close-up lenses that mounted on the front of the camera. The same is possible with the THOR-002 and Thermal Master will even be offering a close-up lens in the THOR-001 camera kit to save users having to construct such a supplemental lens. OEM lenses tend to be better than DIY versions made from inexpensive ZnSe laser focus lenses. I have decided that I will not test the PCB imaging capabilities of the THOR-002 camera in the main review as that is not its intended use. I will, however produce an annex to the review that shows what can be achieved with the THOR-002 camera once a close-up lens is fitted (Spoiler: it performs very well indeed !)As this is a general purpose camera that will find use in many areas of daily life, I will be testing its imaging capabilities in some of those use cases and providing plenty of pictures for readers to view and consider. As the old saying goes...."a picture speaks a thousand words" and as we are testing a camera, pictures are the obvious way to judge its imaging performance. The camera is fully radiometric so I have tested its measurement accuracy and also its minimum focus distance. The results of those tests will be seen in there respective review sections.There is an obvious question that may be asked by readers, that is, given the choice of buying a FLIR E5 PRO, that the THOR-002 is intended to compete with, or the Thermal Master THOR-002, which would I buy ? For me the decision is simple, I would buy the THOR camera as it has higher resolution, higher frame rate, excellent build quality and all at a lower cost. I cannot believe that I have just typed that as I love FLIR's professional and Industrial cameras, but Thermal Master have created some serious competition to FLIR's Ex range of cameras. Will I be selling my FLIR E60+ ? ... Hmmm, No, I love that camera and have a huge soft spot for it. It offers different capabilities to the THOR-002 so they compliment each other in my lab. I sold my FLIR E4(E8+) some years ago and have often thought of buying another. That is no longer necessary now that I have the THOR-002

content: Measurement accuracy test.In order to test the measurement accuracy of the THOR-002, it was switched on and allowed to warm up for 30 minutes. This ensures the most stable and accurate measurements. The camera was then aimed at a known accurate Black Body temperature reference that had been set to 40.0 Degrees Celsius and allowed to stabilise for an hour before the test. The camera was provided with the Black Body Emissivity of 0.97 and the 0.5m target distance from its lens.The measurement was taken and the THOR-002 reported a Black Body temperature of 37.3 Celsius which is an error of -2.7 Celsius. This result was unexpected so I emailed my findings to Thermal Master for comment. Thermal Master quickly established that my pre-release camera was indeed producing an unacceptable measurement error. What I liked about this interaction with Thermal Master was their professionalism. They worked with me to prove the error and "owned it" once it became clear that my particular camera has a measurement accuracy issue. My THOR-002 is one of an initial 12 models made for testing and something appears to have gone amiss during its calibration. As is often said, it is not when things are going well that you should judge a companies attitude, it is when things go wrong that you see their true colours. In this case Thermal Master were understandably concerned that I had a less than perfect example of their camera to test and very honest about the cause of the error.I asked Thermal Master to test one of their final production release cameras and to send me images of the results. They kindly sent me some pictures of a THOR-002 undergoing a measurement accuracy test in their R&D lab. As may be seen from those images, the THOR-002 meets its +/-2 Celsius or +/-2% accuracy specification. Note that the Black Bodies in this Thermal Master test are calibrated for an Emissivity of 1.0, hence the setting of 1.0 Emissivity on the camera during their test.Thermal Master Lab Test Results10 Celsius Source = 10.5 Celsius on camera40 Celsius Source = 41.0 Celsius on camera50 Celsius Source = 51.1 Celsius on camera120 Celsius Source = 120.5 Celsius on cameraI have no reason to doubt the claimed accuracy of measurements made by current production release THOR-002 cameras and the Thermal Master testing confirmed that my camera is at fault, rather than the production calibration process.

content: :palm:kFocus and Resolution TestThe THOR-002 camera is equipped with a fixed focus lens that provides a focussed image between 30cm and infinity. The combination of 256x192 pixel microbolometer FPA and 40 Degree HFOV lens produces an IFOV of 2.79 mrad. This choice of lens FOV on the THOR-002 is good. Other cameras have wider FOV lenses and higher IFOV figures that result in a loss of detail when working at a distance from the target.The spot sizes (single pixel size on target) for various working distances are given below....Distance to target Spot Size on target30cm 0.84mm50cm 1.4mm1m 2.8mm5m 14mm10m 28mm50m 140mm100m 279mmWith a Close-up lens that does not change the IFOV50mm 0.14mm63mm 0.18mm80mm 0.22mm100mm 0.28mmSpot size Calculation = IFOV(mrad)/1000 x Distance(mm)THOR-002 IFOV = 2.79mradExample :2.79/1000 = 0.00279For distance = 2m : 0.00279 x 2,000 = 5.58mm spot size for one pixel on the target.For accurate measurements the recommended minimum number of pixels on the target is 3 x 3 (9 pixel square).The THOR-002 performed as expected during the focus and resolution test with no matters of concern noted. X3 was switched on during the Grille test image captures. In retrospect, I should have switched off the X3 mode to avoid image processing effects. I will rerun the test but have uploaded my images until I have replacements.

content: Internal views of the THOR series cameraThanks to the FCC web site we have images of the THOR cameras interior. These images are low resolution but reveal interesting details about the design and build quality. Note the use of brass threaded inserts in the case securing towers. This is good to see and a sign of quality. There is a seal between the case halves and behind the trigger to provide fluid and dirt ingress protection. A cast aluminium chassis is used to mount the microbolometer core and the main PCB. This metal chassis is used to help dissipate thermal energy from the rear of the microbolometer core and so improve temperature stability and reduce the chances of a thermal gradient across the microbolometer. As can be seen, the conventional Li-Ion battery is accessible to be changed if it ever fails. Detail of the IC's used on the main PCB is not visible but I would expect to find a decent SoC and some memory devices as is common in modern thermal imaging cameras. I see nothing in the FCC images to cause me any concern about the cameras internal design. It looks well organised and constructed.

content: The image analysis softwareThermal Master offer a free download of Windows PC Image Analysis software called Thermal Smart OS that may be used with the saved images from the THOR-002 camera. There is currently no Linux or MAC version of the Analysis software.Images on the cameras micro SD card are stored in a Radiometric JPEG format that may be viewed on any JPEG image viewer but the Thermal Master Image Analysis software is needed to access the RAW pixel data that the image file also contains. Images are transferred to the PC from the camera and then selected for analysis. The software provides measurement functions that are not found on the camera so can enhance the users understanding of a saved thermal scene.The Thermal Master Image Analysis software offers the following measurement functions:1. Spot Measurement2. Line Measurement3. Rectangle ROI Measurement4. Circle ROI Measurement5. Polygon ROI Measurement6. Differential point Measurement7. Maximum and Minimum temperature in the scene8. Maximum and Minimum temperature of an ROIThermal master have provided some of these measurements functions in the PC software rather than on the THOR-002 camera itself as the PC offers a larger display and easier use of the functions than would be possible on the camera. The THOR-002 could be considered the data collection tool and the PC software the detailed image analysis tool for investigations and reporting.Once a radiometric image is loaded into the software it may be manipulated as desired by the user to make measurements, change palette or image mode (IR/Visible/Fusion/PIP or iMix). The software also permits the user to adjust the level and span shown in the image. This is the feature that I asked to be added to the THOR-002 camera.A report creation tool is included in the software. The user may select what will be included in the report. The options are as follows:IR ImageVisible Light ImageLine ChartHistogramROIDevice (camera) informationEnvironment ParametersUser NotesOther ImagePlain Text Entry

The THOR-002 camera may be configured as a Wi-Fi Hot Spot to which a mobile phone or tablet may connect. The ThermalSmart APP provides the user with a live streamed image the same as that shown on the cameras display. The APP also provides access to the cameras saved images for viewing and saving. No image analysis functions are present in the APP so it is basically a live and saved image remote viewer.The THOR-002 produces a 5GHz Hot Spot when Wi-Fi is enabled. It does not produce a 2.4GHz Hot Spot.

content: The Pictorial section of this review begins here.....A picture speaks a thousand words so I have captured a number of thermal images over the past months to show what the THOR-002 produces in various real World situations. The first set of images are at the request of Thermal Master who wanted to see how their THOR-002 compared to the venerable FLIR E60+ that I have.THOR-002 Vs FLIR E60+A comparison of images produced by the THOR-002 with those produced by my FLIR Mk1 E60+(upgraded from E40)Whilst this may seem an unfair comparison due to the higher, 320 x 240 pixel, resolution and excellent Germanium lens of the E60+, Thermal Master were keen for me to carry out this test.My FLIR E60+ is configured for its best possible NETD and has the FKIR 45 Degree HFOV wide angle supplemental lens fitted to bring its FOV close to that of the 40 Degrees HFOV of the THOR-002.The result of this real world comparison is shown below.Target :House1. FLIR E60+ with built in lens (25 Degrees HFOV)2. FLIR E60+ with Supplemental wide angle lens fitted (45 Degrees HFOV)3. THOR-002 - X3 mode off (256x192 pixels)4. THOR-002 - X3 mode on (AI driven enhancement to 512x384 pixels)Target :Street1. FLIR E60+ with Supplemental wide angle lens fitted (45 Degrees HFOV)2. THOR-002 - X3 mode off (256x192 pixels)3. THOR-002 - X3 mode on (AI driven enhancement to 512x384 pixels)I have to report that the IPS display of the THOR-002 far outperformed that of the somewhat elderly FLIR Mk1 Exx series camera. The IPS display is so crisp and clearThe matt touch screen on the FLIR E60+ really does degrade the display performance in outdoor conditions.

content: ANNEX AUse of the THOR-002 for electronic PCB analysisThe THOR-002 is intended to be a "General use" thermal camera that can produce excellent thermal imagery in a variety of scenarios. Like many such cameras, including those from FLIR, a close-up lens is needed in order to image modern PCB components in any detail. The stated minimum focus distance of the THOR-002 is 30cm and whilst this does provide an image of a PCB of adequate resolution to show "hot spots" it cannot provide the finer detail without a supplemental lens to provide close focus of ~100mm.In order to test the THOR-002 with a close-up lens I installed a professional AGEMA/FLIR 100mm FL close-up lens and a DIY ZnSe 63mm FL CO2 laser focus lens. OEM supplied lenses tend to outperform DIY ZnSe CO2 laser lenses but it is a common solution to the challenge of close-up thermal imaging when on a tight budget.The images that follow show just how well the THOR-002 performs when a close-up supplemental lens if attached to it. I was very impressed with the imagery that the camera produced with both the AGEMA/FLIR lens and the DIY ZnSe lens. Attaching the close-up lens provides a "night and day" difference when working on modern PCB's. I have been using the THOR-002 (with 100mm FL close-up lens fitted) for PCB analysis tasks for the past month. It sits on my lab bench waiting for the next patient that needs thermal analysis. Thermal Master do produce their own excellent close-up lens that attaches to the front of the camera using a neat clip assembly. I understand that the close-up lens is only available as part of the enhanced performance THOR-001 kit. The THOR-001 has a minimum focus distance of 80mm when the supplemental close-up lens is fitted. There is also an additional menu entry on the THOR-001 to tell it that the close-up lens is in use and to apply a correction to measurements.The images of PCB's at a distance of 30cm with no close-up lens fitted reveals the limitation on detail imposed by have 256x192 pixels and a 40 Degree lens producing an IFOV of 2.79 mrad. This is no criticism of the THOR-002, it is just Optical Physics in action. To obtain the needed detail, the camera needs to be closer to the PCB and the camera cannot provide a focused image at such a close distance. As has been stated, a supplemental close-up lens facilitates the closer working distance to reveal greater detail.Once the close-up lens is fitted, the individual components and IC's may be clearly images and their thermal profile analysed. I have absolutely no hesitation in using the THOR-002 for PCB analysis once the close-up lens is attached. With a DIY ZnSe lens fitted to the THOR-002 camera, a small measurement error will be introduced due to the transmittance figure of the close-up lens. For very accurate measurements, this will need to be considered and corrections applied. Commercial users may wish to consider purchasing the enhanced performance THOR-001 kit with its 80mm FL OEM close-up lens and associated support in the camera menu.A Philips DVB receiver was used as the test subject for the THOR-002 PCB thermal analysis tests. To provide context, some visible light images of the PCB are attached below.

content: Annex BA real World example of THOR-002 PCB inspection performanceI had a pair of FLIR MIRV cooled thermal scopes on my bench for diagnostics and repair. The first unit would not respond when powered and switched on. Upon investigation it was clear that the scope was drawing excessive current.The THOR-002 camera was switched on and immediately revealed the cause of the problem to be a large Tantalum capacitor on the main power rail that was getting warm. After adding the AGEMA/FLIR 100mm FL close-up lens to the camera, the exact location of the failed capacitor was clear. The second thermal scope has a failed temperature sensor in its detector FPA assembly but a brief check of the power PCB with the THOR-002 revealed that it had two Tantalum capacitors on the main power rail that were getting warm. These capacitors were in the early stages of failure and would have eventually drawn excess current. The THOR-002 had made discovery of these failed capacitors a simple task and without a decent thermal camera the second MIRV's failing capacitors might have gone unnoticed.I attach some images and an MP4 video from the MIRV repair and a video showing the failed Tantalum capacitor heating up after power is applied to the PCB. The other rectangular component adjacent to the capacitor is a diode that is in series with the supply to the capacitor, hence why it heats up quickly. The images are not the best as I was just recording the fault without taking time to avoid hand shake etc.

content: Conclusion...After over 2 months of testing I remain very impressed with the THOR-002 camera. The build quality and performance exceeds what I would expect from a 256 x 192 pixel 25fps thermal imaging camera with a retail price of $299. The unit feels just like my FLIR camera in my hand and the IPS display is a thing of beauty that I wish was present on many of my other thermal cameras. I was initially disappointed that the THOR-002 did not have a manual Level and Span mode but Thermal Master were quick to add this for me. The AI based X3 Super Resolution mode is a very interesting function that I would have expected to be only on the higher specification THOR-001 but Thermal Master have generously provided it on both camera models. I can honestly state that it has been a pleasure to test this new camera and it deserves to do very well in the marketplace. It looks professional and performs very well in many different imaging situations. In the future, if anyone asks for my advice on buying a well equipped thermal camera at a sensible price point, the THOR-002 will be my recommendation. FLIR have some serious competition in the form of Thermal Master and that can only be good for consumers.Fraser

My comments on the camera appear in the review section under another name (Bill Spohn) as they have protected my identityThat is nice to see and I can state that Thermal Master have posted my honest comments without editing or changes. I have given Thermal Master my permission to use any material I produce whilst testing the THOR-002.

content: The “Techradar” review of the THOR-002 has just been released…….https://www.techradar.com/cameras/thermal-master-thor002-thermal-imaging-camera-reviewBe warned, there are some wrong assumptions and errors in the Techradar review. The author does not have the information about what X3 Super Resolution is on the THOR-002 so thinks it is simple interpolation or image stacking. This is incorrect. He also keeps referring to the THOR-001 as an earlier model, not so. The THOR-001 has not been released yet ! I was a little disappointed with the Techradar review as it appears to misunderstand the intended market that the THOR-002 was designed for and the need for a clear large display and rugged build, just like that found on the more expensive FLIR Ex and Exx series cameras. I have never heard any professional users criticise a FLIR Ex or Exx series camera for being too large, bulky or heavy ! The THOR series is not trying to fit in with the extant budget thermal camera offerings, such as the UTi260B and PC210, it is standing out from the “crowd” and at a very reasonable price too.Fraser

It looks like from your review that is amandatoryoption for what most of us on this forum would be using the camera for. Perhaps you could suggest to Thermal Master that they include the lens with the camera, or at least make available at a reasonable price, for early purchasers of this camera.

content: Stray Electron,I asked Thermal Master about the availability of the OEM close-up lens as an accessory that may be bought separately for the THOR-002. The response was that they do not intend to offer it as a purchasable accessory and the THOR-002 does not have the Close-up lens menu entry to support a supplemental lens (likely measurement corrections). It is very much like the situation with the FLIR Ex series. FLIR never offered an OEM close-up lens option for that camera seriesThe THOR-001 is intended for use by those who need its enhanced specification and the close-up imaging capability. It’s $599 price point likely reflects its intended market segment and the THOR-002 appears under priced in order to fit into its intended market segment. I have no insight into Thermal Masters marketing strategy but I do think the THOR-002 is an excellent price at the moment and the additional 5% discount for forum members is a nice bonusI think those who can afford it, such as commercial users, might buy the THOR-001 and the rest of us would likely go for the still excellent THOR-002 and then make a close-up lens for it, as we have had to do with many other thermal cameras in the past. I have already purchased the Cloudray 20mm diameter, 63mm FL ZnSe meniscus lens for that projectFraser

And since the Thor-1 has better specs than the T-2 then I think that I may wait and get a T-001. That's assuming that I'm willing to part with $600 for a camera. At $300 a thermal camera might be a bargain but at $600 then I'm going to have think about it some more. The lack of an adequate close up ability in the T-001 is sort of a non-starter for me.AND I notice that photo that they show on Amazon of the close up of a PCB board is from a T-001 and not a T-002! To me, that's deliberately misleading to the buyers! The first photo in the third image states that it was taken with a Thor-001 but none of the others say which camera that they were taken with!!!

It is not just a simple CO2 laser focus lens and is made of Chalcogenide IR glass. The Meniscus dome is also very pronounced, unlike my ZnSe lenses. Thermal Master had to wait quite some time to get the close-up lens into stock for their THOR-001 so it may be made for them by a 3rd party. It also reduces the FOV of the camera to 29 Degrees x 21 Degrees.Fraser

content: ixfd64,I have replaced the Li-Ion battery in cameras like the Unit-T UTi260B without difficulty as I am a tech. I agree that some users would not feel confident in dismantling the camera to carry out such a task but, unlike Apple, the OEM has not made disassembly nigh on impossible without causing damage (modern iPads). I suspect that a built in battery was chosen in the design stages to simplify sealing the cameras case and reduce production cost for a competitive retail price.On the topic of removable batteries, my FLIR cameras have a removable battery but the price that was being asked for them was scandalous. Opening the sealed battery packs to fit new cells was no fun either. Personally I prefer to undo a number of screws in a cameras casing, lift out and disconnect a standard commercial Li-Ion cell and install a new one. The cost is very reasonable and no breaking open ultrasonically sealed plastic battery cases required. Even modern laptops have gone to internal batteries that require some disassembly to access them for changing.One very valid case for a removable battery pack is run-time. If a camera is going to be used mobile for an extended period of time, it can be an advantage to be able to change the battery pack when it becomes discharged. That said, the THOR series have an 8 hour run-time which is pretty good. If a longer Run-time is needed whilst remaining mobile I suppose an external high capacity USB power bank could be connected to the cameras charging socket, but this does mean opening the protective rubber ports cover.Fraser

content: Not sure where to post this, but since macro-lens business for the Thor-002 has been discussed in this thread, this seems to be the place to be. I cobbled together a 3d-printable macro-lens holder for this camera, allowing the use of low-cost ZnSe lenses originally designed for beam focusing in laser cutters. The attached thermal image was taken with this holder and a lens with focal length of 50.8 mm. The image shows a TQFP-48 chip surrounded by 0603 and 0805 parts as well as a transistor in a SOT223 package. In my opinion, this is very usable for the usual board bring-up and debugging and I may even consider a larger focal length.This is a press-fit for the lens and the holder fits into the empty slot of the pelican case. The model is not perfect, the geometry of the clips/bracket is not quite right and when mounted, the holder can be tilted slight which requires manual alignment. Then again this is good enough for me so I probably won't improve it further.Link to the model on printables, including STL, STEP and Fusion 360 resources and links to the lens I used:https://www.printables.com/model/1368182-macro-lens-holder-for-thermal-master-thor-002

The solid casing and the dual-layer lens protection really do give confidence when using it outdoors, especially around dust and moisture. I also appreciate that the trigger and keypad controls make it easy to operate with one hand, which is a big plus compared to phones or dongles where you need to tap the screen.One small thing I’d add for anyone curious: during extended sessions, the unit stays surprisingly cool for a 640×480 device. I’ve used it for building inspection on a hot day and it didn’t throttle or show thermal drift, which is impressive. The rubber cover for the USB/MicroSD port is indeed snug — just be careful not to lose it if you’re swapping cards often.

content: I have to agree, it is a lot of extra money for a close-up lens. I considered this whilst testing the THOR-001 against the THOR-002.When first released, the 001 and 002 appeared to be almost the same with the 001 having additional measurement points, palettes and the macro lens capability. I asked for manual level and span to be added to the THOR cameras as such is, IMHO, essential in a semi-pro/pro thermal camera. Thermal Master have added that manual level and span function but only on the 001 as that is being marketed as the higher specification model for professional users. Whilst this disappointed me, it was a way for Thermal Master to increase the differential between the two models. The 001 states a better measurement accuracy in its specification but +/-2C vs +/-1.5C is a difference that only the buyer can decide is important to their use scenario.The macro lens supplied with the 001 is very nice quality. It is a purpose designed thick meniscus lens that provides some magnification as well as close-focus at 80mm. I suspect that such a custom lens was quite expensive to obtain for Thermal Master. That lenses production actually delayed the release of the THOR-001 to market as it is not just a simple ZnSe laser focus lens. The attachment method of the macro lens is good and the quality of materials used are excellent.When the THOR-002 was released it was discounted to US$299 and that actually seemed low for its specification and build quality. The THOR-001 has always been significantly more expensive but compared to an equivalent resolution FLIR product, it remains an excellent VFM deal. It is also a 25fps thermal camera and that is an advantage over the FLIR <9fps models like the Ex series.With all this said, I have not released my THOR-001 review due to ill health and I found an issue with the THOR series that I need Thermal Master to investigate before I release the review. I am confident in my testing methods and review process but it is only fair to let the Manufacturer investigate and respond.Fraser
