4.3. Emissivity
The emission factor of an object strongly influences the
measurement result 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, so the
default 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 with the
wrong emission factor setting. 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:
