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.
Benefits
Innovative NOx or NO₂-to-NO converters enable a gas a analyser , which typically measures only NO, to accurately determine the total concentration of nitrogen oxides (NOx, which is the sum of NO and NO₂). They convert the nitrogen dioxide present in exhaust gases or flue gases into a single form: nitrogen monoxide.
