Continuous Emissions Monitoring Systems (CEMS)

With over 3,000 CEMS installations in the field worldwide, Rosemount Analytical combines the expertise and field-proven technologies with the most rugged sample conditioning and extraction systems in the industry to provide superior measurement accuracy and repeatability. Designed in consideration of CEM regulations as specified in clean air laws around the world, including U.S EPA 40 CFR Part 75 and 40 CFR Part 60, we help you meet data reporting requirements, maintain emissions compliance, and ensures certification and compliance with your local and international regulatory agencies.
Typical Components Monitored

Sulfur Dioxide (SO2) Nitrogen Monoxide (NO) Nitrogen Dioxide (NO2) Carbon Dioxide (CO2) Oxygen (O2)

Carbon Monoxide (CO) Total Hydrocarbon (THC) Hydrogen Sulfide (H2S) Opacity

Pre-Engineered CEMS Solutions Rosemount Analytical offers a cost effective pre-engineered CEMS solution to monitor stack gases for regulatory compliance. They are designed to perform the required daily zero and span checks automatically and unattended. Automatic calibration makes it less costly and time consuming to meet the environmental requirements for daily validation of the system.

Customized CEMS Solutions Rosemount Analytical CEMS solutions range from pre-engineered, packaged systems to more complex custom engineered systems that measure multiple gases using data acquisition and handling.
