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. 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.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. |
