Hart Scientific, American Fork, Utah, a division of Fluke Corp, offers the new 4180 series of precision infrared calibrators with sample calibration procedures for Fluke thermometers built in.
Hart Scientific’s model 4180 has a temperature range of –15 °C to 120 °C, with radiometric (non-contact infrared) display accuracy as good as ± 0.40 °C; and model 4181 measures from 35 °C to 500 °C, with radiometric display accuracy also as good as ±0.35 °C. Users do not need a pedigree in physics to perform high-quality infrared thermometer calibrations.
Features include emissivity, size-of-source effect, target stability and uniformity, six-inch target diameter, traceable radiometric calibration, and compensation for the emissivity settings of the radiation thermometer being tested.
