Emissivity: Emissivity coefficient
The level of infrared emissions given off by everything depends on the specific material and surface. This
factor is determined by the emissivity coefficient (0.10 ... 1.0). For accurate measurements, it is absolutely
essential that the emissivity coefficient is set first. The emissivity coefficient can either be custom set or
selected based on the predefined emissivity coefficients from the material list.
