D-R 320 Dust Monitor
Brand: DuragThe 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.
