Durag D-R 320 Dust Monitor

The new scattered light dust monitor to detect lowest to medium dust concentrations in dry flue and process gas.

The D-R 320 is based on the back-scattered light principle. Thereby the light of a red laser diode illuminates the dust particles in the measuring volume of the flue gas duct. The light scattered backward by these particles is detected and evaluated.

A unique feature of the D-R 320 is the automatic background light compensation with means of a patented optical system with dual detector. This allows for an easy and quick Installation without any adjustment. A light trap is not required.


  • Single-sided installation without optical alignment
  • Automatic background light compensation without light trap
  • Automatic zero and reference point check
  • Automatic contamination control and correction
  • Integrated purge air regulation and purge air control
  • QAL1 certified according to EN 15267-3
  • Compliant with US EPA 40 CFR 60 PS11
  • Lowest certification range 0...7.5 mg/m3
