Continuous Opacity Monitoring System

Emissions Compliance and Process Performance Monitoring
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.

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

- Cement Manufacturing
- Incineration Plants- Waste, Hazardous waste and Sewage Sludge Incineration Plants- Gas, Coal and Co-Firing Power Plants
- Biomass
