Research and development institutions, which rely on valid measuring values as well as mechanical or plant engineers favor to install this infrared device in order to establish a noncontact temperature control system.

The high-power laser of the pyrometer are prepared to measure temperature of non-metallic surfaces. These are for example materials like plastic, lacquers, wood or paper. The infrared-thermometer is used e.g. for controlling temperature by welding of plastic parts as well as for test stations in the automotive sector. The infrared sensor guarantees an accuracy of the whole measuring device of +/- 1% or 1°C.




  • Low and high temperature measurements of smallest spots up from 0.9 mm
  • Double laser aiming marks real spot location and spot size at any distance
  • Optics 75:1 with selectable focus
  • Usable up to 85 °C ambient temperature without cooling and automatic laser switch off at 50 °C
