content: Hi!I won an auction with lots of old test equipment. Probably I'll get these equipments in two or three weeks. But I'm very curious to know what I bought.So I kindly ask you if you can help me to identify any equipment in the attached pictures. Comments about these equipments are welcome, of course!I already identified:1- Yokogawa 2793 - Decade Resistance Box2- HP 54500 Series - 4 Channels Oscilloscope3- HP 3456A - 6 1/2 Digits Multimeter4- Wayne Kerr B642 - Auto Balance Universal BridgeThank you!Regards,Rodrigo.

content: I see a coiple of old handheld meters, sihnal generators. Curious to see what the rackmount gear is. The decade resistor looks nice.

content: On the second picture, the two units on the bottom right are the Yokogawa 2560 DC calibration set with its amplifier whose model number escapes me. They're voltage/current generators.I think it was good to 1000V on the voltage range (0.15%) and 30A(0.2%) on the current range.

content: Thank you for all replies!Yes, the images are horrible, but are the only ones at the moment. Sorry.@deadlyloverYou nailed it! They are an Yokogawa DC Calibration set.So, now we have:1- Yokogawa 2793 - Decade Resistance Box2- HP 54500 Series - 4 Channels Oscilloscope3- HP 3456A - 6 1/2 Digits Multimeter4- Wayne Kerr B642 - Auto Balance Universal Bridge5- Yokogawa 2553 - DC Voltage Current Standard6- Yokogawa 2563 - Voltage Unit7- Yokogawa 2564 - Current Unit@LabSpokaneThese were put in a public sale in Brazil, probably because deactivation of a old lab.

content: Be very careful what you are calling "Very Old" test gear. Some of us were using test gear long before most of that came out. To me "Very Old" equates to WWII to mid 50's vintange

content: Yes, some aren't that "very" old, about 70's or 80's I guess. Somewhere around 30 or 40 years old.But those in the big boxes in the third image, behind the paper sheet (Lote 50 inscription), seems really very old...

content: Quote from: rodpp on February 13, 2015, 09:45:37 amBudenberg is now part of Wika as far as I know:http://www.wika.co.uk/dh_budenberg_en_co.WIKAMake sure the weight set is included with the deadweights tester, these will be very heavy. In some cases the weights are calibrated with the base as a system. Since deadweight testers are mechanical they do not 'drift' so quickly as electronic items and so even very old ones are useable unless damaged or stored very badly. The manufacturer recommended re-calibration check is usually 3 or 5 years.

content: Directly behind the oscilloscope, facing backwards is a recirculating water bath can't tell the brand or model due to it facing away from the camera. My guess based on size is it will be single function, most common heating only, but it might be cooling only. You can see the back recirculating connectors in the first image, a side profile in the second image and more of the body in the third image. It would likely be used for holding things at a precise and constant temperature (water transfers heat better). It is missing the lid which goes over the bath portion.It will look something like this from the front, just older:http://www.vgdusa.com/circulating.jpgAlso, in the first image, the handheld device on the top right (large, grey with many buttons) is a Symbol Barcode Scanner (possibly the model SPT1700). It's basically an old Palm Pilot PDA encased in plastic with the needed barcode and networking features. Next to it is an MSA Pulsar+ Single Gas sensor (this appears to be an O2sensor.

content: Two maybe identifications:See the attached image.I think the blue and white thing is an IKA magnetic stirring hot plate. There are quite a few similar model-lines with dozens of models so I can't tell anymore than that (Check the RCT model for an idea of what it might look like). I've used dozens of these in my labs and they are OK devices. See this link to anhttp://staff.washington.edu/wbeaty/stir1.jpg. Notice the white cap where you can insert a rod for attaching ring clamps and things like that. It is also present in the attached image.Next to it, might be a handheld lab UV light. It has the right look and buttons based on the ones I have used in my lab. Not entirely sure on this but it looks right.

content: Thank you @PedroDaGr8, another two great identifications!It is a good chance that the magnetic stirring hot plate is the RTC model, because the proportion of the circular disc and the base, and the little circular screw on the corner.Regarding the handheld UV light, I searched and don't found the same model because there are hundreds, but it's a very good guess.So updating again:1- Yokogawa 2793 - Decade Resistance Box2- HP 54500 Series - 4 Channels Oscilloscope3- HP 3456A - 6 1/2 Digits Multimeter4- Wayne Kerr B642 - Auto Balance Universal Bridge5- Yokogawa 2553 - DC Voltage Current Standard6- Yokogawa 2563 - Voltage Unit7- Yokogawa 2564 - Current Unit8- Budenberg - Deadweight Tester9- Unknown Brand - Deadweight Tester10- Wavetek 171 - Synthesizer/Function Generator11- Tektronix DC503/TM501 - Universal Counter12 - Simpson 360 - Digital Volt-Ohm-Milliammeter13- PROTEK CM108 - Handheld Capacitance Meter14- Unknown Brand - Recirculating Water Bath15- Symbol SPT1700 - Barcode Scanner16- MSA Pulsar+ - Single Gas O2 sensor17- AVO TT166 - Transistor Test Set18- IKA RTC - Magnetic Stirring Hot Plate19- Unknown Brand - Handheld Lab UV Light

Could be only the probable brand, or probable function, then I'll search trying to find it.Thank you all for the identifications.
