Continuous Emission Monitoring Systems (CEMS)

Data integrity and accuracy to avoid fines and penalties

Continuous Emission Monitoring Systems (CEMS)

What is Continuous Emission Monitoring Systems (CEMS)

Improving the reliability of your data, reducing costs, maintenance and environmental issues are the top priorities for industrial organizations and businesses today. The purpose is to avoid potential fines and penalties.

Continuous Emission Monitoring Systems (CEMS) are mandated by environmental agencies to meet air quality permit requirements such as MCERTS, TV, and US EPE Part 60 & 75. CEMS is a powerful and robust software application package that can store, analyze, visualize and report environmental data from a variety of sources. The main goal of Continuous Emission Monitoring Systems (CEMS) is to demonstrate environmental regulatory compliance of various industrial sources of air pollutants.

CEMS is a system to collect, store, visualize and report industrical process-related data from a variety of sources. The CEMS system is capable to monitor various processes on an intermittent or continuous basis.

Enable Continuous Improvement With CEMS

Ease of Use​

Reduce the amount of time operators spend using the system and allows them to get their work done quickly and effectively.


Eliminate single points of failure with a distributed architecture.

Predictive Maintenance

Reduce costly repairs by detecting problems through calibration control, tracking, and reporting.

Scalability and Expandability

The ability to transmit all the analog and digital channels over the TCP/IP network greatly increases scalability and expandability.


Save money on PLC unit, programming, cabinet space, and long-term maintenance.

Remote Access and Monitoring

A standardized way to connect people, processes, and technology with a consistent interface.

How to improve your environmental performance with CEMS

Challenges managing limits on emissions

  • Ever-changing regulatory standards
  • Technology options
  • A significant percentage of Continuous Emission Monitoring Systems (CEMS) rely on obsolete or discontinued systems
  • The EPA mandated 95% availability means systems can only be down 18 days per year
  • Analyzer technicians being responsible for a larger number of analyzers than a decade ago.
Decarbonization, emissions

As environmental regulations become more stringent, companies and municipalities are facing immense investment and development challenges
