4180 Series precision infrared calibrator

03 March 2008

Fluke - Hart Scientific has introduced the 4180 Series Precision Infrared Calibrators. The two new models, 4180 and 4181, utilise the same size targets used and recommended by thermometer manufacturers, and features special design technology that assists non-experts in productively performing high-quality infrared thermometer calibrations.

The new Fluke 4180 has a temperature range of -15°C to +120°C with radiometric (non-contact infrared) display accuracy to ±0.25°C, while the Fluke 4181 measures from 35°C to 500°C with radiometric display accuracy to ±0.3°C.

The 4180 series puts fast, portable and high-quality calibration within the reach of first time users - as well as experienced 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, 15cm 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 “IR Cal 101,” a technical note available from Hart Scientific and in the Hart Scientific Guide to Infrared Thermometer Calibration.
