In order to check infrared radiometer calibration, you will need at least two targets each with a known temperature and emittance. A simple solution is to use a container of ice water and a container of boiling water with a coupon of Scotch PVC electrical tape affixed to the container’s exterior surface. The size of each target must exceed the spot measurement size of the instrument being calibrated. Container temperatures may be ascertained with a thermometer, thermocouple or contact radiometer.
Once targets have been prepared, use the following procedure:
A heated blackbody simulator can be used to check instrument calibration at higher temperatures. Because radiometer calibration is not user adjustable, it will be necessary to return it to the manufacturer should you find your instrument is out of spec.
Radiometer calibration will be the subject of SuccessIRies 202, one of two short courses being held on January 19, 2020, at the IR/INFO Conference. Attendees who bring their imager can calibrate it for free while at the conference.
