Sensor Calibration

Apogee SIF series infrared radiometers are calibrated in a temperature controlled chamber that houses a custom-

built blackbody cone (target) for the radiation source. During calibration, infrared radiometers (detectors) are held

in a fixture at the opening of the blackbody cone, but are thermally insulated from the cone. Detector and target

temperature are controlled independently. At each calibration set point, detectors are held at a constant

temperature while the blackbody cone is controlled at temperatures below (12 C), above (18 C), and equal to the

detector temperature. The range of detector temperatures is -15 C to 45 C (set points at 10 C increments). Data

are collected at each detector temperature set point, after detectors and target reach constant temperatures.

All Apogee analog infrared radiometer models (SIF-100 series) have sensor-specific calibration coefficients

determined during the custom calibration process. Unique coefficients for each sensor are provided on a

coefficient certificate (example shown below).

Calibration overview data are listed in the box in the upper left-hand corner, sensor specific coefficients are

listed in the box in the upper right-hand corner, temperature errors are shown in graph, and calibration date is

listed below descriptions of calibration procedure and traceability.
