Nitrogen Oxides Analyzer (NO, NOX, NO2)

The outcome is an ultra compact and light- rack 3U, easy-to-use, chemiluminescence based analyzer capable of measuring nitrogen oxides at ppb levels. Applied to nitrogen oxides measurement, Chemiluminescence corresponds to an oxidation of NO molecules by O3 molecules. The return to a fundamental electronic state of the excited NO2 molecules is made by luminous radiation, detected by the PM tube.
