Continuous Opacity Monitoring System

Emissions Compliance and Process Performance Monitoring
DURAG D-R 290
The DURAG D-R 290 is a certified optical transmission monitor for compliance under U.S. EPA 40 CFR 60 PS1 to measure the opacity or dust concentration of flue gases with medium to high dust concentrations.

The D-R 290 operates using the double-pass method according to the auto-collimation principle. The light beam traverses the measuring path twice. The attenuation of the light beam by the dust content in the measuring section is measured and evaluated.

Features
-
Continuous and contact-less measurement
- Automatic zero and span check
- Automatic measurement and correction of contamination of optical surfaces
- Extremely powerful and stable super-wide band diode (SWBD) light source
- Extremely low-maintenance
- Fail-safe shutters with purge air monitoring as option
- Compliant with US EPA 40 CFR 60 PS1 and ASTM 6216
