  • Power stations
  • Cement plants, the metallurgy, and wood industries, chemical industry etc.
  • Waste incineration plants
  • Monitoring of dust filter plants.

Great New Features
  • Integrated display: Measuring value, threshold value, parameter in probe
  • In-situ measuring procedure with continuous measurement
  • High sensitivity
  • Easy installation on one side of the duct
  • Can also be deployed in thick-walled stone/insulated channels
  • Long lifetime, as there are no moving parts inside the duct
