Accuracy and traceability for infrared measurements
Now it’s easy to increase your IR temperature measurement accuracy with the new 4180/81 Precision Infrared Calibrators from Fluke’s Hart Scientific division. These 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 calibrators simplify calibration because they uniquely compensate for errors caused by thermometer emissivity settings.
New accredited performance for point-and-shoot calibrations
- Calibrated radiometrically for meaningful, consistent results.
- Accredited calibration included
- Accurate, reliable performance from –15 °C to 500 °C
- Large target size of 152 mm (6 in) is required for calibrating most thermometers.
- Light instrument weight of 8.6 kg (19 lbs) makes it easy to lift and carry.
- Intuitive, easy-to-read display that indicates when temperature is stable.

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. 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.
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.

1For 8 um to 14 um spectral band thermometers with emissivity set between 0.9 and 1.0
2The uniformity specification refers to how IR thermometers with different spot sizes both focused at the center of the targer will measure the same temperature.
3The target has a nominal emissivity of 0.95, however it is radiometrically calibrated to minimize emissivity related uncertainties.
