Hart Scientific, a division of Fluke Corporation (USA) announce the arrival of the 4180 series Precision Infrared Calibrators. The two new models, 4180 and 4181, utilize the same size targets used and recommended by thermometer manufacturers and special design technology that assists non-experts in productively performing high-quality infrared thermometer calibrations without requiring a background in physics.
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 as good as ± 0.35 °C.
The 4180 series puts fast, portable and high-quality calibration within the reach of first time users and seasoned metrologists through careful design and calibration. The calibrators address quality issues such as emissivity and size of source effect which are commonly ignored in other calibrators. Features such as target stability, target uniformity,
six-inch target diameter, traceable radiometric calibration, and compensation for the emissivity settings of the radiation thermometer being tested overcome some of the other most common limitations. In addition, sample calibration procedures for Fluke thermometers are built into the instrument to get users up and running with a minimum of training. More information about infrared calibration issues can be found in “Infrared Temperature Calibration 101†a technical note available on the website.
