1For 8 mm to 14 mm spectral band thermometers with emissivity set between 0.9 and 1.0
2The uniformity specification refers to how IR thermometers with different spot sizes both focused at the center of the target will measure the same temperature.
3The target has a nominal emissivity of 0.95, however it is radiometrically calibrated to minimize
emissivity related uncertainties. |
Should your thermometer be calibrated by one of these?
Business decisions costing thousands of dollars are based on the results of your measurements, so they had better be right! It can be very expensive to shut down a line for repairs and maintenance, but it might be catastrophic if the shutdown is unplanned. To stand by your measurements with confidence, you should definitely have your thermometers calibrated.
How to get consistent results:
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 infrared calibrator from Fluke’s Hart Scientific Division.
The 4180 Series of Precision Infrared Calibrators 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 reaches temperatures from –15 °C to 120 °C and the 4181 has a temperature range from 35 °C to 500 °C. Check out the uniformity of the large 152.4 mm (six in) targets shown in the Fluke Ti30 photo. The uniformity and stability are so good that variations can’t be detected with a thermal imager. 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 and each pixel of a thermal imager registers a temperature that needs to be both accurate and consistent across the imager.
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. (See the sidebar below for information about common pitfalls in infrared calibrator accuracy and have a look at our Guide to Infrared Thermometer Calibration to get started quickly with your new calibrator.)
