  • T1200-NOy NOy analyzer

    The T1200-NOy analyzer uses the catalytic conversion chemiluminescence method to analyze NOy in ambient air. According to the basic principles of HJ1043-2019 "Chemiluminescence Method for Automatic Determination of Nitrogen Oxides in Ambient Air", under the action of an external molybdenum conversion furnace, NOy (including NO, NO?, NO?, N?O?, HNO?, HNO?, PAN, etc.) is first converted into NO, and then measure NOy through the reaction of NO and O?.
