SO2 NO CO CO2 O2 anlyser

Used to measure concentration of SO2 ,NO ,CO ,CO2 and O2 from stack or boiler emission gases, in which SO2 ,NO ,CO and CO2 are measured by micro-flow infrared sensors and O2 by electrochemical sensor (optional paramagnetic detector O2 sensor), with optional gas temperature, pressure, velocity etc, calculating combustion efficiency, lambda and so on.
