Fast, accurate and easy-to-use infrared calibrator provides consistent and reliable calibrations
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.
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.
• Calibrated radiometrically for meaningful, consistent results.
• Accredited calibration included
• Accurate, reliable performance from –15°C - 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.

1For 8 µm to 14 µm 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.
