Infrared Calibration Development at Fluke Calibration (364.73 KB)

A flat plate calibrator is one instrument used in calibrating IR thermometers, primarily in the 8 – 14 µm band. One such family of flat plate calibrators is the 418X Precision IR Calibrator from Fluke Corporation Hart Scientific Division. This product is calibrated with a radiometric calibration. To support this radiometric calibration and its traceability, a number of developments have been made at Hart Scientific. These developments include the construction of a new IR calibration laboratory with radiometric traceability.

This paper discusses a number of topics related to the development of IR calibration capabilities at Hart Scientific. These topics include the need for a radiometric traceability for flat plate calibrators, the traceability chain to national laboratories included in radiometric calibrations at Hart Scientific, the development of blackbody cavity baths in Hart’s IR calibration laboratory, and Hart Scientific’s IR uncertainty budgets.
