3 EN pyrometer BP17
The emission ratio can range 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 emissivity.
• The brighter and smoother the surface of a material, the
lower will be its emissivity, 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 become negligible.
Entering a degree of emission as accurate as possible is
indispensable for a precise measurement.
Most organic materials have an emissivity of 0.95. Metals or
shiny materials come with a much lower value.
