Fluke Hart Scientific 4181-156

The Fluke Calibration 4181156 Precision Infrared (IR) Calibrator, 35 °C to 500 °C (95 °F to 932 °F) for infrared thermometers and thermal imagers is fast, accurate, and easy to use. It comes with an accredited calibration, sample calibration procedures for Fluke thermometers built right in, and everything you need to start making high-quality infrared thermometer calibrations. The 4181-156 is the perfect solution for any infrared thermometer or thermal imager within its temperature range.

The Fluke Calibration 4181-156 has a temperature range from 35 °C to 500 °C. Uniformity is important in infrared temperature calibration work because an infrared thermometer will "see" as much as the entire target when placed at the appropriate calibration distance and each pixel of a thermal imager registers a temperature that needs to be both accurate and consistent across the imager.

Lastly, the 4181-156 can meet its specifications without additional emissivity related corrections, leading to legitimate test uncertainty ratios (TUR) as good as 4:1.
