When high accuracy is not necessary, both Isotech's Black Body and Grey Body offer cost-effective solutions for the calibration and testing of infrared thermometers. The QuickCal Black Body infrared calibrator is ideal for rapid and portable checking of infrared thermometers. The Grey Body Model 975 gives fast, accurate results with a larger sensing area, and less emissivity.

A temperature sensor sits just under the target surface and controls the temperature of the source. A custom designed surface sensor is used to set the controller calibration, and a traceable certificate is supplied with each source. Either infrared calibration unit can be programmed for Fahrenheit or Celsius operation.
