Micro air station

1. Overview ofMicro Air Station Products

Micro air station is also called air monitoring micro station and micro air automatic monitoring station. The micro air station is a high-precision atmospheric gridded air quality monitoring system based on electrochemical principles, which can realize continuous and real-time online monitoring of atmospheric environment quality. .

1. Background overview:

The micro-environmental air quality monitoring system is a new online multi-parameter air quality monitoring system produced by our company. It mainly monitors PM2.5, PM10, CO, SO2, NO2, O3, and can also be expanded to include five meteorological parameters, noise and other parameters. Establishing an atmospheric environment data monitoring and analysis system can improve the processing and management capabilities of air pollution monitoring data and provide a decision-making basis for environmental planning and environmental assessment. Mainly used in corporate industrial parks, urban environment monitoring, municipal environment monitoring, mobile environment monitoring, traffic pollution environment monitoring, parks, forest environment monitoring, etc.

The micro-environmental air quality monitoring system can realize online automatic monitoring of regional air quality, and can monitor real-time changes in sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, PM2.5, PM10 and organic volatiles in the environment all-weather, continuously and automatically. , quickly and accurately collect and process monitoring data, which can timely and accurately reflect regional ambient air quality conditions and changing patterns, and provide detailed data and scientific basis for the environmental protection department's environmental decision-making, environmental management, and pollution prevention.
