Application of Various Gas Sensors in Atmospheric Environment Monitoring Station

The super station adopts the fixed point continuous monitoring, the combination of ground monitoring and vertical measurement, the combination of the ground telemetry and the satellite observation, the combination of the conventional monitoring and the high technical means monitoring, constitute the air quality three-dimensional monitoring system, realized the Olympic time to Beijing and the surrounding Three - dimensional monitoring of regional air quality. 

Based on the local environmental management needs, combined with the local topography, meteorological conditions, the type of pollution sources, the local superfluous stations are generally used in urban or regional stations SO2, NO2, CO, O3, PM2.5, PM10 conventional 6 parameters monitoring And other conditions, the new urban or provincial regional transmission characteristics monitoring and monitoring of key pollutants, especially to strengthen the monitoring of photochemical pollution indicators, such as Shanghai, Hubei and other places to build some of the atmosphere super station.

In recent years, Winsen is also vigorously developing the atmosphere monitoring sensor. Winsen atmosphere monitoring sensor has been widely used in domestic multi-gas super stations.
