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. |

Features
- Fast, portable and easy to use.
- Correct target size for most thermometers.
- Calibration solutions from –15°C to 500°C (5°F to
932°F).
- Radiometrically calibrated for traceable and
consistent results.

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 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). 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.
