Detects lowest to medium dust concentration

D-R 320 Dust monitor for industrial stacks

Proven Technology and Easy Installation

The D-R320 is a high quality dust monitor to detect lowest to medium dust concentrations in dry flue and process gas. Based on the back-scattered light principle, the light of a red laser diode illuminates the dust particles in the measuring volume of the flue gas duct. The light is then scattered backward by these particles and are detected and evaluated.
A unique feature of the D-R 320 is the automatic background light compensation including an optical system with dual detector. This allows an easy and quick installation without any adjustment nor light trap.
