Remember Kirchhoff’s radiation law!




The infrared radiation recorded by the thermal imager consists of:

  • the radiation emitted by the measuring object
  • the reflection of ambient radiation and
  • the transmission of radiation by the measuring object

The greater the difference between the temperature of the measuring object and ambient temperature of the measuring object and ambient temperature and the lower emissivity is, the greater the measuring errors are. These errors increase if the emissivity setting is incorrect.
