The Air Quality Online Monitoring System primarily consists of a
particulate matter measurement device, gas monitoring modules, and
a data acquisition and wireless transmission unit. Combined with
monitoring platform software, it enables functions such as air
quality publishing, comprehensive data analysis, pollution
exceedance alarms, urban environment photography, and video
surveillance.>>FeatureHigh Integration: Can simultaneously integrate sensors for particulate matter, SO₂,
CO, NO₂, O₃, TVOC, and meteorological five-parameter sensors.
Optical Sizing: Utilizes optical particle sizing technology for simultaneous
monitoring of PM₁.₀, PM₂.₅, PM₁₀, and TSP.
Constant Flow Control: Incorporates flow feedback for constant flow control, ensuring
sampling volume stability and enhancing accuracy.
Built-in Protection: Features sheath gas protection and gas path protection functions.
Professional Design: Structural design by professional design institutes for easy
installation.
Tiered Air Paths: Features dual-pump air paths with main channel for particulates
and auxiliary channel for gas modules.
Data Stability: Equipped with temperature and humidity sensing, gas
cross-interference algorithms, zero drift compensation, and
calibration across measurement ranges.
Dynamic Dehumidification: Can be equipped with a dynamic heating dehumidification sampling
system to avoid data distortion in humid environments.
Data Transmission: 4G, RS232/RS485.
Data Export: Features USB port and/or SD card slot, supporting local data
export (includes local storage with capacity >530,000 records).
Weather Resistance: Protection against rain, snow, and lightning.
Traceability: Traceable to NIST (National Institute of Standards and
Technology).
Resume Transmission: Features power failure protection and data resume/re-transmission
upon network restoration.
Information & QC: Includes device information management, data management, and data
quality control functions.
Local Display: Equipped with LCD display and local debugging functions.
Multi-stage Filtration: Incorporates a two-stage or higher filtration system to prevent
foreign matter from affecting sensor accuracy and precision.
Service Life: Main unit >10 years; Particulate Matter Sensor >5 years;
Gas Sensors >2 years.
Calibration/Zeroing: Supports automatic/manual zero calibration and calibration
functions.
