Reflected temperature information:
Using this offset factor, the reflection is calculated out based on the
low emissivity, and the accuracy of the temperature measurement
with infrared instruments is improved. In most cases, the reflected
temperature is identical to the ambient air temperature. Only when
objects with strong emissions and much higher temperatures (such
as ovens or machines) are in proximity to the object being
measured should the radiation temperature of theses heat sources
be determined and used (e.g. using a globe thermometer). The
reflected temperature has little effect on objects with high
emissivity.
Using the PC software, other materials can be imported into
the instrument from an existing list.
