CEMS

Continuous Emission Monitoring System

CEMS, the “Environmental Eye” for Source Emissions

The Continuous Emission Monitoring System (CEMS) is an integrated system to measure flow, dust, concentration of air pollutants (such as SO2, NOx, CO, CO2, THC and O2 etc), and other parameters in accordance with the applicable regulations for the emission source. Required parameters depend on the type of stationary source. HORIBA has delivered a lot of Continuous Emission Monitoring Systems (CEMS) in accordance with the standards of Europe, the U.S., and other countries for emission gas measurement items required by environmental regulations. We offer total solutions based on sate-of-the-art technology we have accumulated over the years, from measurement equipment such as exhaust gas analyzers to software including data processing system design. 

Division: Combustion
Manufacturing Company: HORIBA, Ltd.

HORIBA has been providing stack gas analyzers for more than 50 years along with developing various analysis technologies and sampling systems. HORIBA has supplied more than 100,000 stack gas analyzers worldwide and maintains the largest market share in Japan for power applications. Parameters required by regulations in thermal power generation are continuously measured at the stack and reported to the government by CEMS (Continuous Emission Monitoring System). HORIBA contributes to the efficiency of your measurement system with its highly accurate analyzers and systems compliant with local, national, and international regulations, based on many years of trust and experience.
