AQS800 Air Quality Station

AQS800 Air Quality Stations

The AQS800 – Air Quality Station 800 is a multi-parameter environmental grid monitoring station; a specialized small instrument for urban grid environment monitoring. It can monitor temperature, humidity, PM2.5/10, CO, NO2, SO2 and O3 elements. The system uses modules for flexible configuration, has a small size and a low cost, and is suitable for gridding, intensive, and refined layout requirements.
