Measurement of NO, NO2, and O2 at the SCR inlet

The gas conditions include high dust and high temperature, so the gas analyzer installation location is important. Abrasion and clogging can occur due to particulate load and temperature in both process and ambient environments. The GM32 in-situ gas analyzer measures NO and NO2 concentration, as well as pressure and temperature in the exhaust duct and delivers true values in real time – directly, quickly, and without gas sampling. The ZIRKOR200 in-situ gas analyzer provides a reliable and rapid measurement of oxygen for standardized reporting.
