Action Step
Write down the emissivity. 12
➲ Please note the following:
■
Avoid forced convection
■
Look for a thermally stable surrounding that will not generate spot reflections
■
Use high quality tape that you know is not transparent, and has a high emissivity
you are certain of
■
This method assumes that the temperature of your tape and the sample surface
are the same. If they are not, your emissivity measurement will be wrong.
16.3 Reflected apparent temperature
This parameter is used to compensate for the radiation reflected in the object. If the
emissivity is low and the object temperature relatively far from that of the reflected it
will be important to set and compensate for the reflected apparent temperature cor-
rectly.
