The surface temperature probe (thermocouple type K) features a  thermocouple strip, which guarantees a fast response time and enables  measurements to be carried out on uneven surfaces.

It has a very large measuring range and can be used for many different applications:

  • Detection of thermal bridges in walls
  • Maintenance and checking of machinery
  • Process monitoring of production steps
  • Adjustment of heating systems (radiators, pipes, boilers)
  • Quality checks
