AIDBUCKS A530 Entry-Level Non-Contact Digital Infrared Thermometer Temperature Gun -26&deg;F to 986&deg;F (-32&deg;C ~ 530&deg;C) Laser Aim Support Adjustable Emissivity Indoor Outdoor Use - Black Red Better Accuracy - Accurately and quickly measures surface temperatures within 500ms. By setting the emissivity of your IR thermometer to match the object you are measuring, you obtain a more accurate temperature reading. Distance Spot Ratio: 12:1; Emissivity: 0.95(fixed). Measures in Celsius or Fahrenheit (Range: -26 to +986 / -32 to +530). Functional Diversity - Auto power off function to extend the battery life, and along with low battery indicator; This temperature gun can save 32 groups of readings of former measurements, you can easily take them for compare; MAX/MIN temperatures function; Use the SCAN mode to detect the surface temperature of moving objects. Smart Design - A built in Laser gives you the precision to hone in on the exact space you want to measure. A large LCD screen with backlit provides a better visibility. lasers can be turned on and off independently. When you hold the device it's very lightweight with a comfortable grip. Various Usages - Practical for both indoors and outdoors use, the Infrared Thermometer A530 is simple to operate and easy to store. Use it in the kitchen for instant surface temperature measurements, scan for insulation leaks in your home, or check your cars cooling system, catalytic converter, brakes, and tires and so on. Note - The measured temperature for humans or animals will not be correct. Not for medical use. FDA, FCC approved and RoHS compliant. 1.The Maximum/Minimum value indication tells you the measurement of maximum/minimum temperature value (Click on the Mode button); 2.Emissivity setting function can match the emissivity of the thermometer to the objects emissivity which makes the measurement data more accurate. 3.The apparatus retains the recent measured 32 sets of data which makes it easy to measure different objects temperature in the same time. 4.The C/F conversion function, laser point and the backlit provide more convenience to the measurement.
