AMS-500 Chemiluminescence NOX Analyzer can detect low concentration (ppb level) NO, NO2 and NOX in ambient air. It is the of the gaseous analyzer of the ambient air quality monitoring system . Its core measurement module is an ozone generator, chemiluminescence reaction chamber and photomultiplier tube . Its principle is to measure the concentration by measuring the fluorescence released by the chemical reaction between NO and O3.
