A flat plate calibrator is one instrument used in calibrating infrared (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 presentation discusses the research done to establish IR calibration capabilities. Among the topics discussed are the need for 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.
