Dust and Opacity Monitor

Monitoring particulate emissions in flue gas streams with DURAG GROUP’s PM-CEMS (Particulate Matter - Continuous Emission Monitoring System) and opacity monitors ensures regulatory compliance, protects the environment and improves operational efficiency. Real-time data enables proactive maintenance, reduces downtimes and promotes sustainable practices for industries.

D-R 909 is a wet stack dust monitor suitable for particulate measurement after wet scrubbers, Flue Gas Desulfurisation (FGD) plants, Wet Electro-Static Precipitators (WESPs) and other processes where the flue gas falls below the dew point. It is a highly reliable PM CEMS monitor, used for continuous extractive measurement of dust contents in wet and sticky exhaust gases. The monitor complies with international standards such as US EPA 40 CFR 60 PS 11, EN 15267, EN 14181 (QAL 1 certified), UL 61010-1 (cETLus certified), etc. 

D-R 290 is suitable for continuous, contactless dust and opacity measurement at medium to high concentrations in dry flue and process gases. It can be adopted for difficult plant conditions. Exceeds USEPA (United States Environmental Protection Agency) and ASTM (American Society for Testing and Materials) standards.

D-R 320 is an ideal solution for continuous, contactless measurement of low to medium dust concentrations in dry flue and process gases. It is also suitable for corrosive gases and potentially explosive atmospheres.

D-R 808 is a certified and approved PM-CEMS providing very high quality monitoring of very low to medium particulate concentrations in dry flue gas flows.
