Fluke 4180/4181 Infrared Temperature Calibrators (-15 to 500°C)
Product Description
The 4180 Series of Precision InfraredCalibrators 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 Infrared Temperature Calibrator reaches temperatures from –15 °C to 120 °C and the 4181 Infrared Temperature Calibrator 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.
Overview
Key features
- Accredited radiometric calibration included
- Accurate, reliable performance from -15 °C to 500 °C (Between 4180 and 4181 models)
- 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.
