AQS918 Air Quality Station
AQS918 Air Quality Stations
The AWS918 – Air Quality Station 918 is a multi-parameter environmental grid monitoring station; a specialized small instrument for urban grid environment monitoring. It can monitor temperature, humidity, wind speed, wind direction, air pressure, PM2.5/10, SO2, NO2, O3, CO, H2S, NO, TVOC 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.
