The degree of emission is used to describe the energy radiation
characteristics of a material.
A material's degree of emission depends on various factors:
• composition,
• surface condition,
• temperature.
The degree of emission can be between 0.1 and 1(, in theory).
The following rule of thumb can be assumed:
• When a material is rather dark and its surface texture matt, it
probably has a high degree of emission.
• The brighter and smoother the surface of a material, the lower
will be its degree of emission, presumably.
• The higher the degree of emission of the surface to be
measured, the better it is suited for non-contact temperature
measurement by use of a pyrometer or thermal imaging
camera, since falsifying temperature reflections can be
neglected.
Entering a degree of emission as accurate as possible is
indispensable for a precise measurement.
Most organic materials have a degree of emission of 0.95. Metals
or shiny materials come with a much lower value.
