4.4. Emissivity
The emission factor of an object influences the measurement result
massively and can be adjusted from 0.01 to 1.00. Many common
measurement objects (such as wood, water, skin and textiles) have
a matte surface and high infrared radiation, which is why the
standard emission factor of this device is set to 0.95. For semi-matt
objects, the emission is lower at about 0.85 and at half-glossy
objects even lower, at about 0.6. shiny objects have the lowest
infrared radiation and therefore indicate a wrong reading if the
emission emission setting is wrong. Usually, the infrared radiation at
glossy surfaces is about 0.3.
Deviating emission factors can be changed before each
measurement in the menu and taken from the following table:
