  • 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, NO₂, NO₃, N₂O₅, HNO₂, HNO₃, PAN, etc.) is first converted into NO, and then measure NOy through the reaction of NO and O₃.
