No matter what low-temperature infrared thermometer you have, you can quickly and accurately check its calibration in the field or laboratory with Everest’s Low-Temperature Calibration Source (Model 1000).  It is a small, hand-held, self-contained, portable unit that checks the precision of any infrared thermometer with ±0.3ºC or ±0.5ºF accuracy.

Along with the accuracy of the Model 1000 Calibration Source you also have ease of use.  You can easily turn the source on and aim the infrared thermometer with its Emissivity set at .98 at the specially treated target on the Calibration Source.  Then, compare the readout on the infrared thermometer or sensor to the digital readout of the target’s liquid crystal display. 

There is also a toggle switch on the Model 1000 that lets the end user choose either ºF for Fahrenheit or ºC for Celsius.  

The blackbody surface of the instrument has been prepared using proprietary high-emissivity aluminum oxide, with a configuration that uses re-entrant concentric rings.  This allows the infrared energy to bounce back and forth between the rings, giving a blackbody surface closest to a perfect configuration as possible.

The Low-Temperature Calibration Source is powered by a nine-volt battery that can be replaced easily by the user.  The operator needs only to remove the four screws that are holding the back to the front of the calibration source, remove the nine-volt battery and replace it with a new one.
