Converting NO2 to NO for NOx measurements
Fields of application
Combustion and power plants, waste-to-energy and incineration, steel mills, furnace control, continuous emission monitoring systems, research laboratories and other processes.
Features
Innovative NOx or NO2-to-NO converters enable a gas analyser, which usually measures only NO, to accurately determine the total concentration of nitrogen oxides (NOx, which is the sum of NO and NO2). They convert the existing quantity of nitrogen dioxide in the exhaust or flue gas into a single form, namely nitrogen monoxide.
