Emissivity
Emissivity Description
The emissivity of the infrared thermal camera 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 to 0.95 when rough objects that emits energy more easily are
measured. For semi-matte objects that give out less energy, the emissivity
value is usually 0.85 and the emissivity value for semi-gloss objects is 0.6.
Shiny objects have a lower emissivity value, which is usually set to 0.3 at the
time of measurement. A proper emissivity value is very important in
measuring target temperatures . 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
results.
Emissivity Setting
The product provides 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 using the "Custom" option (refer to the table "emissivity of
common materials").
The operating steps are as follow:
