Basic Infrared Thermometry Theory - Relating to the use of the Product
Typically, infrared (IR) thermometers have not been used for measurements requiring low
uncertainties. Their application has been for use at extremely high temperatures and in applications
where accuracy is less important than repeatability.
As infrared thermometers and our understanding of their advantages improve, both absolute accuracy
and calibration become more important. This section gives a brief explanation of some important
issues surrounding the use and calibration of IR thermometers and how this information relates to the
use of the Product.
Apparent Temperature
The Product is calibrated using a radiometric calibration. The main display temperature is based on this
radiometric calibration. This temperature shows the user what an IR thermometer with a given
emissivity setting should read. This is called apparent temperature. The apparent temperature is
defined as the temperature an IR thermometer set to emissivity ( ε ) should read when measuring the IR
calibrator's surface.
In other words, the display temperature shows what temperature the target appears to be to the IR
thermometer.
