Overview

The GR-MAQMS mobile environmental air quality continuous automatic monitoring system uses optical detection technologies such as infrared, ultraviolet, laser, chromatography, and light scattering, X-ray and beta ray detection technologies, data acquisition, transmission, and automatic control technologies to achieve continuous automatic monitoring of environmental air quality. The data can be used as a basis for evaluating air quality. This system can monitor the concentration values of factors such as SO2, NOX, CO, O3, TSP, PM10, PM2.5, PM1.0 in the ambient air, as well as meteorological parameters. It can also expand the monitoring of special factors such as heavy metals and volatile organic compounds in the air. The system adopts modular design, mobile, with mature technology, stable performance, high measurement accuracy, wide dynamic range, and easy maintenance and upgrading. This system can be applied to the construction of air quality background stations, regional stations, and characteristic stations.
