Calibration Traceability
Apogee SI series infrared radiometers are calibrated to the temperature of a custom blackbody cone held at
multiple fixed temperatures over a range of radiometer (detector/sensor body) temperatures. The temperature of
the blackbody cone is measured with replicate precision thermistors thermally bonded to the cone surface. The
precision thermistors are calibrated for absolute temperature measurement against a platinum resistance
thermometer (PRT) in a constant temperature bath. The PRT calibration is directly traceable to the NIST.
