You know what's at stake. It costs thousands to shut down a production line for maintenance and more if the shutdown is unplanned. The credibility of a technician's recommendation to shut down is only as good as his infrared thermometer and its calibration. Two major requirements are accuracy and consistency.

How to get accurate and consistent results:

Need to know how to calibrate infrared thermometers? Get up to speed fast! Read "Infrared Temperature Calibration 101" by Fluke's Hart Scientific Division for reliable information. Even those infrared thermometers that cannot be adjusted can benefit from a calibration that demonstrates the consistency and validity of your results. Try an interactive online demonstration to better visualize topics like emissivity, scatter, and radiometric calibration.

A trusted calibration means less worry, fewer questions and more time being productive. To get more reliable, traceable, and consistent results, buy a 4180 or 4181 Precision Infrared Calibrator. Consistent and accurate calibrations require large targets because of scatter in infrared thermometer lenses. Reliable calibration of the measurement surface measures the energy radiated by the surface and not just its internal temperature. Called "radiometric calibration," it calibrates the infrared temperature of the target which depends on emissivity (the largest and most neglected source of error in infrared temperature calibrations).

These easy-to-use infrared calibrators are high-accuracy, portable and compensate for the emissivity of infrared thermometers in a simple way with unique technology. Model 4180 has a temperature range of –15 °C to 120 °C, with radiometric display accuracy as good as ± 0.40 °C, and Model 4181 measures from 35 °C to 500 °C, with radiometric display accuracy as good as ±0.35 °C.
