What is a Continuous Emission Monitoring System (CEMS)?

A Continuous Emission Monitoring System (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation, graph, or a computer program to produce results in units of the applicable emission limitation or standard.

CEMS are required under some of the EPA regulations for either continual compliance determinations or determination of exceedances of the standards. The individual subparts of the EPA rules specify the reference methods that are used to substantiate the accuracy and precision of the CEMS.

Quality assurance procedures in Appendix F to 40 CFR 60 are used to evaluate the effectiveness of quality control (QC) and quality assurance (QA) procedures and the quality of data produced.

The Importance of CEMS Probe Maintenance

The continuous emissions monitoring probe is the initial contact with the sample being drawn for monitoring. Preventative maintenance can help keep your probe functioning and provide you with years of reliable data and service. Our Field Service Technicians recommend inspecting probes annually to ensure they operate properly.
