The emissivity of the product can be adjusted from 0.01 to 1.00 with the default
value of 0.95. Many common objects and materials (such as timber, water, skin
and textile fabric) can reflect the heat energy effectively. So it is easy to obtain
relatively correct measurement value. The emissivity is usually set as 0.95
when the coarse objects that are easy to give out energy. For semi-matte
objects that give out less energy, the emissivity is usually about 0.85 and the
emissivity of semi-gloss objects is 0.6. The shiny objects are divided into
materials with low radiation coefficient. The emissivity is usually set as 0.3 at
the time of measurement. Correct setting of the value of emissivity is very
important for you to carry out the most correct temperature measurement. The
surface emissivity will produce giant impact on surface temperature measured
by the product. Understanding the surface emissivity will enable you to obtain
correct temperature measurement result.
The product is provided with four types of object measurement modes:
Coarse object (0.95)
Semi-matte object (0.85)
Semi-shiny object (0.60)
Shiny object (0.30)
According to the characteristics of the measured objects, users may set the
emissivity value through the “self-define” option (please refer to the table of
“emissivity of common materials”).
