1For 8 mm to 14 mm spectral band thermometers with emissivity set between 0.9 and 1.0.
Includes stability, uniformity, emissivity,
calibration and drift.
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.
H ow 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 8 to 14 mm infrared
thermometer within its temperature range.
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.) 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.
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. |
