It is fixed type model can continuous monitor concentration of SO2, CO2, O2 , NO and CO components in the flue gases for longtime. It is based on the micro-flow infrared method for SO2 ,NO ,CO ,CO2.This model is fixed type can sample gas for longtime. This model is designed as 19 inch enclosure physical dimension to easy install.

Boiler, furnace exhaust emission gas and combustion efficiency monitoring, cement production line process and security monitoring, Continuous Emission Monitoring System (CEMS).
