MEGA CEMs Stack Engineering Drawing

Ohio Lumex CEM Systems

The Ohio Lumex Continuous Emissions Monitoring (CEM) System is a group of instruments and equipment needed to measure the concentration of flue gas emissions as required by local environmental regulators. 

Depending on the type of fuel and combustion process, several gas components, including CO, NOx, and SO2 are typically continuously monitored in the flue gas at the stack, along with dust, gas flow, temperature and O2, and occasionally H2O. 

The data is collected by Data Acquisition System (DAS) for further processing, data storage, reporting and communication to the environmental authorities and stakeholders.


        We serve a wide range of industries and applications, including:

Coal-Fired Power

Gas Turbines

Pulp and Paper




Bio Diesel


Waste Incinerator




Bio Mass



Iron and Steel
