14. Emissivity
The emissivity of the surface of a material is its effectiveness in
emitting energy as thermal radiation. The emissivity of the product
can be adjusted from 0.10 to 1.00 with the default value of 0.95. Many
common objects and materials (such as timber, water, skin and textile
fabric) will reflect heat energy, so it is easy to obtain high accuracy as
a result.
Choosing the correct setting of the emissivity value of different
objects and materials is very important for achieving accurate
temperature measurement. The surface emissivity will greatly affect
the measured temperature and therefore adjusting the emissivity
value to match it is essential.
