Infrared thermometer
test and calibration

Infrared thermometer calibrations can be accurate
with the proper setup and planning. It's important
to choose a calibrator with a radiometrically
calibrated target that is large enough to
accommodate the recommended calibration
distance of common infrared thermometers,
along with their various fields of view.
Common errors include pressing the infrared
calibrator too close to the hot surface of the
calibrator or simply moving the infrared
thermometer back and forth until the desired
reading is achieved.
The manufacturer will have calibrated the
infrared thermometer at a specific distance with a
source that meets certain size requirements and
has a specific emissivity (often but not always
0.95) . To have a meaningful calibration that
determines whether the instrument continues to
operate within its design specifications, those
conditions need to be reproduced as closely
as possible.
