Product Introduction
The AQ7021 Ammonia (NH3) Analyzer (hereinafter referred to as the AQ7021) is an analytical instrument based on the principle of chemiluminescence, designed for measuring the concentrations of nitrogen monoxide, nitrogen dioxide, nitrogen oxides, and ammonia in the air.
This NH3 analyzer enables continuous monitoring of nitrogen oxides (NO, NO₂, NOx (NO+NO₂), NH₃, NT (NOx+NH₃)) present in the atmosphere. The concentration of NO₂ can be calculated based on the measured NO and NOx concentrations, while the NH₃ concentration is derived from the NT and NOx concentrations, with all data available for output. The analog outputs for NO, NOx, NO₂, NH₃, and NT concentrations are displayed in real-time on the main interface screen. Additionally, by equipping the device with an optional RS-232C interface, data communication can be achieved.
