Fluke Calibrator Video

October 24, 2010

Emissivity makes a temperature difference for infrared thermometers. In the YouTube video below, Frank Liebman, an engineer with Fluke Corporation’s Hart Scientific Division demonstrates the impact that surface emissivity has on temperature measurement and temperature calibration using a modified Fluke blackbody calibrator and Fluke Thermal Imager. We were surprised to see that no one commented [...]
