Product Description
AQ7021 Ammonia (NH₃) Analyzer High Precision Chemiluminescence for Industrial Emissions
Product Overview
The AQ7021 Ammonia (NH₃) Analyzer is an advanced analytical instrument based on chemiluminescence technology, specifically designed for precise measurement of nitrogen monoxide, nitrogen dioxide, nitrogen oxides, and ammonia concentrations in ambient air.
This high-precision NH₃ analyzer enables continuous monitoring of atmospheric pollutants including NO, NO₂, NOx (NO+NO₂), NH₃, and NT (NOx+NH₃). The system calculates NO₂ concentration from measured NO and NOx values, while NH₃ concentration is derived from NT and NOx measurements. All concentration data is available for real-time output and displayed on the main interface. With the optional RS-232C interface, comprehensive data communication capabilities are supported.
