It is economical portable type which mainly based on electrochemical sensors to measure the volume concentration of CO, CO2 ,O2 ,SO2 ,NO2 ,NO and HC in flue gas and to figure out excess air coefficient. This product has high precision, small volume, it is convenient to carry, simple to operate and it is extensively applied in steel, chemical, energy conservation monitoring, energy efficiency evaluation and other fields. Applications Combustion and emission control research or certification of Continuous Emission Monitoring System (CEMS), combustion efficiency monitoring for various industrial furnaces or refuse incinerator and boiler.
