Fluke Hart Scientific 4180 & 4181 Infrared Calibrator Provide for Consistant Results
Consistant Results via Calibration with Fluke 4180 & 4181
Even those infrared thermometers that cannot be adjusted can benefit from a calibration that demonstrates the consistency and validity of your results. A trusted calibration means less worry, fewer questions and more time being productive. To get more reliable, traceable, and consistent results, buy a Precision 4180 or 4181 Infrared Calibrator from Fluke’s Hart Scientific Division.

Hart Scientific 4180 & 4181 Infrared Calibrators Provide Accuracies to ± 0.35 °C 
In addition, with accuracies as good as ± 0.35 °C, the Hart Scientific 4180 & 4181can meet their own specifications without additional emissivity-related corrections, leading to legitimate test uncertainty ratios (TUR) as good as 4:1. (See the sidebar below for information about common pitfalls in infrared calibrator accuracy and have a look at Fluke's Guide to Infrared Thermometer Calibration to get started quickly with your new calibrator.) The accuracy specification is the combined result of the radiometric calibration uncertainties, target stability and uniformity, and the expected drift over a one year calibration interval.
Common Pitfalls in Infrared Thermometer Calibration
If the target size is too small, the thermometer will not read the right temperature. This problem, called size of source effect, is addressed by the large, 152.4 mm (six in) target of the 4180 series, which was designed to accommodate the field of view and calibration geometry requirements of certain common infrared thermometers used in the field, lab and process control. Some people are misled by the accuracy statements on IR calibrators because they are not familiar with the concept of emissivity. Look for calibrators with a “radiometric calibration” so that accuracy will be straightforward and uncomplicated by emissivity-related errors.
Application Note
For more information on emissivity, size of source effect and radiometric calibration, see Hart Scientific application note “Infrared Temperature Calibration 101” or choose a calibrator like the 4180 series that you know has already addressed all of these issues |
