Wahl Black Body Temperature Calibration Sources are controlled and predictable, featuring targets with dull, black surfaces for an emissivity as close to 1 as possible.

Built-in or stand-alone digital temperature controllers with each unit provide accurate, stable temperatures while displaying the temperature readings of the calibration source. The heated plate or cavity provides a target of known temperature and emissivity, and virtually any infrared thermometer with a spot size diameter less than the cavity size can be calibrated.

Wait for the temperature of the target area to fully stabilize before beginning calibration.
