Fluke’s 9132 and 9133 infrared calibrators are designed to meet the precise needs of infrared thermometer and thermal imager users. These portable blackbody sources offer fast heating and cooling, stable temperatures, and radiometric accuracy—making them ideal for field and lab environments alike.
A blackbody calibrator (or blackbody source) is a device that emits thermal radiation with high emissivity, typically near 1.0. This makes it behave closely to an ideal blackbody, emitting radiation according to Planck’s law.
Blackbody calibrators are essential tools for ensuring the accuracy of:
By aiming a device under test at the precisely controlled blackbody target, users can verify and adjust readings to ensure accuracy and compliance with calibration standards.
