This gas analyser (ZPA) is used to measure gas concentrations of NO, SO2, CO2, CO, CH4 and O2. The compounds NO, SO2, CO2, CO and CH4 are measured by non-dispersive infrared, while O2 is measured by the electrochemical, paramagnetic or zirconia method. Optimum use as an analysis unit for measuring waste combustion exhaust gases from boilers and incinerators, or gases from various industrial furnaces.
