Accuracy and traceability for infrared measurements
Now it's easy to increase your IR temperature measurement accuracy with the new 4181 Precision Infrared Calibrators from Fluke Calibration. These infrared temperature calibrators give more consistent, accurate and reliable calibrations because emissivity is radiometrically calibrated, and the target size minimizes size of source effect errors. In addition, these infrared calibrators simplify calibration because they uniquely compensate for errors caused by thermometer emissivity settings.

The 4181 Infrared Temperature Calibrator 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.

Emissivity, blackbodies and graybodies
A true blackbody calibration source would usually be a long cavity with a narrow opening. Unfortunately the opening is usually too narrow to be useful for calibrating common infrared thermometers which require a large target size for an accurate calibration. The advantage of a true blackbody calibration source is that the emissivity is precisely known. Whereas traditional flat plate calibrators have emissivities with uncertainties too large for meaningful calibrations of most thermometers. That is why the 418X Precision Infrared Thermometers are radiometrically calibrated to correct for uncertainties caused by emissivity and heat loss at the surface of the "blackbody" calibration source.

Includes: Report of Calibration (NVLAP Accredited), power cord, user's guide, documentation CD, target cover and serial cable.
