The Air Quality Continuous Online Monitoring System is designed to meet the ambient air quality monitoring needs. Developed in accordance with national or relevant standards, this system is primarily used for real-time monitoring and evaluation of urban ambient air quality. It measures six key air quality parameters: PM10, PM2.5, O3, NO2, SO2, and CO.
The Air Quality Continuous Online Monitoring System comprises sampling devices, analytical instruments, quality control equipment, meteorological systems, sub-station data acquisition software, and central servers. It offers high sensitivity, mature technology, excellent stability, and low maintenance requirements.
It enables 24-hour continuous monitoring of ambient air quality, capable of real-time detection of gaseous pollutants such as sulfur dioxide, nitrogen oxides, carbon monoxide, and ozone; particulate matter including PM10 and PM2.5; and meteorological parameters. This provides a real-time, continuous reflection of regional air quality conditions. The substation data acquisition system collects and stores monitoring data, transmitting both monitoring results and equipment status information to the central computer either periodically or in real-time according to instructions from the central server. The system adopts a modular integrated architecture where each unit operates relatively independently as a self-contained system, ensuring stability and reliability. Standardized digital interfaces connect the units, guaranteeing the stable and dependable operation of the entire system.
