CEMS Analyzer Systems

Optimum solutions to the measurement and monitoring of various pollutants like SO2,NOx, CO, CO2, NH3, HCI, HF, THC, Mercury, etc. Based on the vast experience gained in such systems, Chemtrols today provide solutions on technology platforms of either Dilution Extractive, Hot Extractive or In-situ measurement.

Dilution System
Sample is extracted and diluted with zero air in the probe. Since, dilution takes place within the probe, there is no need for a heat-traced sample transportation line.

Hot - Wet Extraction System
Sample is extracted from stack / duct through a heated filter. Blow back arrangement provided for cases where there is high dust load. Extracted sample is transported using heat-traced line to the sampling system.

In-Situ Instruments
An in-situ gas analyzer sits directly at the measurement point on the stack / duct. Both, cross duct and probe measurement techniques are available.
