Traditional CEMS
Control Analytics, Inc. offers integration of its principal's products as a value added service.

Continuous Emissions Monitoring Systems (CEMS) are used to provide data for compliance with regulatory requirements for the control, monitoring and reporting of pollutant emissions. CEMS can include monitors for CO, CO2, H2S, NO, NO2, SO2, O2, THC, Hg, HCl or Opacity.

CEMS are either in-situ, the measurement is performed in the stack or duct, or extractive, where the gas is removed from the stack or duct and transported to the analyzers.

Extractive CEMS can be either straight extractive, utilizing a vacuum pump to draw the sample from the stack to the CEMS; or dilution extractive, where a precision eductor uses very clean air to extract a sample, at the same time dilute it, then deliver the sample to the analyzer (s).

The primary equipment and services provided by ICAC member companies include: gas analyzers, sample gas conditioning systems, probes, sample lines, calibration gases, data acquisition and reporting systems, CEMS (sole-source suppliers), portable stack gas analyzers and stack testing services. Over the years CEMS have proven themselves to be very reliable, providing the users with data that may be used to improve their process as well as to comply with regulatory requirements.
