Product Description
The AQMS‑09 Ambient Air Quality Monitor Station is specially optimized for hydropower project environmental supervision. It continuously monitors Noise, TSP, PM2.5, PM10, PM1, TVOC, together with meteorological indicators including Temperature, Humidity, Rainfall and Wind Speed, etc.
Suitable for hydropower construction sites, dam sites, aggregate stockyards, underground tunnels, powerhouses and waste residue yards. It captures real‑time data of construction dust, noise pollution and volatile organic compounds generated by painting & equipment operation.
Equipped with dynamic heating humidity compensation and cross‑interference compensation function, the unit ensures stable & accurate data under high‑humidity tunnel and outdoor construction conditions. Data is uploaded to cloud platform via 4G network with breakpoint resume, data effective rate over 99%. Supports over‑limit alarm and linkage with external LED display and alarm light.
It helps engineering teams carry out environmental impact assessment, construction‑period pollution control and long‑term ambient air monitoring for hydropower & water conservancy projects.
