8. Product description

a) Function

Infrared thermometers measure the surface temperature of an object. The sensor on the product records the heat
radiation emitted, reflected and transmitted through the object, and converts this information into a temperature value.
Emissivity is used to describe the energy emission characteristics of a material. The higher the emission level, the
more radiation a material can emit. Many organic materials and surfaces have an emission level of approx. 0.95.
Metallic surfaces or shiny materials have a lower emission level. This will cause an inaccurate reading. For this
reason, a matt black layer of paint or matt adhesive tape should be applied to metallic shiny surfaces.
