9.13 Setting the emissivity as a custom material
9.13.1 General
Instead of specifying a surface property as matt, semi-matt or semi-glossy, you can specify
a custom material from a list of materials.
For more information about emissivity, see section 15 Thermographic measurement tech-
niques, page 43.

9.14 Changing the emissivity as a custom value
9.14.1 General
For very precise measurements, you may need to set the emissivity, instead of selecting a
surface property or a custom material. You also need to understand how emissivity and re-
flectivity affect measurements, rather than just simply selecting a surface property.
Emissivity is a property that indicates how much radiation originates from an object as op-
posed to being reflected by it. A lower value indicates that a larger proportion is being re-
flected, while a high value indicates that a lower proportion is being reflected.
Polished stainless steel, for example, has an emissivity of 0.14, while a structured PVC
floor typically has an emissivity of 0.93.
For more information about emissivity, see section 15 Thermographic measurement tech-
niques, page 43.
