Continuous Emissions Monitoring Systems (CEMS) are used to measure flue gases from stationary sources at a wide variety of regulated industrial facilities, including power plants, petroleum refineries, petrochemical plants, waste incinerators, pulp and paper producers, and many others. The types of air pollution measured from these sources vary widely based on the industry and process, and many are regulated by government agencies around the world.

​Teledyne API's CEMS gas instruments are specifically designed to meet the stringent standards associated with these critical regulatory requirements. TAPI analyzers enable you to pass performance testing in accordance with regulatory standards such as Part 75 or Part 60 in the US as well as their international equivalents.​ ​
