Fluke Calibration 4180/4181
Precision Infrared Calibrators

  • Fast, portable and easy to use
  • Correct target size for most thermometers
  • The 4180 reaches temperatures from:
    –15°C to 120°C (5°F to 248°F)
  • The 4181 has a temperature range from
    35°C to 500°C (95°F to 932°F)
  • Radiometrically calibrated for traceable and consistent results
  • Large 152.4 mm (six in) targets
  • Comes with an accredited calibration from one of the world’s most trusted temperature calibration laboratories
  • Uniformity and stability are so good that variations can’t be detected with a thermal imager

Business decisions costing thousands of dollars are based on the results of your measurements, so they had better be right! It can be very expensive to shut down a line for repairs and maintenance, but it might be catastrophic if the shutdown is unplanned. To stand by your measurements with confidence, you should definitely have your thermometers calibrated.

Even those infrared thermometers that cannot be adjusted can benefit from a calibration that demonstrates the consistency and validity of your results. A trusted calibration means less worry, fewer questions and more time being productive. To get more reliable, traceable, and consistent results, buy a precision infrared calibrator from Fluke’s Fluke Calibration Division.

The 4180 Series of Precision Infrared Calibrators for infrared thermometers and thermal imagers is fast, accurate, and easy to use. It comes with an accredited calibration from one of the world’s most trusted temperature calibration laboratories, sample calibration procedures for Fluke thermometers built right in and everything you need to get started making high-quality infrared thermometer calibrations. This is the perfect solution for any infrared thermometer or thermal imager within its temperature range.

The 4180 reaches temperatures from –15 °C to 120 °C and the 4181 has a temperature range from 35 °C to 500 °C.The uniformity and stability are so good that variations can’t be detected with a thermal imager. 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.

In addition, with accuracies as good as ± 0.35 °C, the 4180 Series can meet its specifications without additional emissivity-related corrections, leading to legitimate test uncertainty ratios (TUR) as good as 4:1.
