testo thermal top tip #6



When using a thermal imager; remember these guidelines:


  • The emissivity of a material depends heavily on the structure of the surface of the material
  • Note the correct emissivity setting according to the covering on the surface of the measuring object
  • Avoid measuring on wet surfaces or surfaces covered with snow or frost
  • Avoid measuring on loose-lying soiling (distortion of temperature by air pockets)
  • When measuring smooth surfaces in particular, be aware of any possible sources of radiation in the vicinity (e.g. sun. heaters etc.)
