Setting Emissivity And Reflected
Temperature Coefficient (RTC)
Emissivity
Emissivity is a term use to describe energy emitting characteristics of materials and has a value
ranging from 0 to 1. Emissivity values approaching
zero are typical for things with a high reflectivity,
like a mirror. Low reflectivity materials (such as
items painted flat black) have emissivity values
approaching 1. Emissivity is material-specific and
must be adjusted for correct measurement results. Improper emissivity values can cause significant temperature errors.
Non-metals (paper, ceramic, gypsum, wood,
paints and coatings), plastics and food typically
have high emissivity, which means that the surface temperature can be easily measured using
infrared.
Because of their low or non-uniform emissivity,
bright metals and metal oxides only have limited
suitability for infrared measurement. Highly inaccurate measurements should be expected. A
remedy for this is coatings that increase emissivity, e.g. paint or emission adhesive, which must
be applied to the object to be measured.
Alternately, the RT-5x, RT-7x and RT-9x thermal
imagers are equipped with ε-Assist, a feature that
will determine the emissivity using the ε-marker
affixed to the target surface.
The following tables gives the standard preprogrammed materials and emissivity and typical
emissivity of common materials for use as a
guideline in setting emissivity.
2. Move the joystick up/down to select the desired material (with permanently set emissivity) and then press OK.
3. Move the joystick up/down until User defined
is selected. Move the joystick to the right until
desired emissivity value is selected. Manually
set value and press OK.
Reflected Temperature Coefficient (RTC)
Information:
The Reflected Temperature Coefficient (RTC) is
calculated based on the Reflected Temperature.
In most cases, the reflected temperature is identical to the ambient air temperature. Only when
objects with strong emissions at much lower temperatures (such as cloudless skies during outdoor
readings) or much higher temperatures (such as
ovens or machines) are in proximity to the object
being measured should the radiation temperature
of these sources be determined and used. The
reflected temperature has little effect on objects
with high emissivity.
Reflected temperature can be determined by:
1. Use a 12" x 12" (300 mm x 300 mm) minimum
