Fluke Calibration 4180/4181 Infrared Calibrator (Formerly Hart Scientific)


- +


The 4180/4181 Series features a large, six inch target designed to accommodate the field of view and calibration geometry requirements of common infrared thermometers that will not accurately test with smaller targets. The 4180 has a temperature range from –15°C to 120°C while the 4181 infrared calibrator has a temperature range from 35°C to 500°C.

The 4180/4181 Series uniformity and stability ensure that variations can’t be detected with a thermal imager. In addition, with accuracies as good as ±0.35°C, the 4180/4181 Series can meet its specifications without additional emissivity-related corrections, leading to legitimate test uncertainty ratios (TUR) as good as 4:1.

The LCD display of the 4180/4181 Series continuously shows the current temperature. The temperature may be easily set with the control buttons to any desired temperature within the specified range. A unique safety feature shows the user when the target temperature is above 50°C letting the user know when it is safe to place the target cover on the instrument and/or move it to a different location. The 4180/4181 Series indicator remains illuminated when the instrument is energized and above 50°C, but with mains power removed, it will flash until the target temperature drops below 50°C. This feature makes the 4180/4181 the safest IR calibrators available.

The 4180/4181 Series include an accredited radiometric calibration report, target cover, user guide, and 9930 Interface-it software with user guide.
