Product Details

WES918 Environmental grid monitoring station is a miniature station developed by our company to measure multi parameter air quality.It can monitor nine environmental factors: PM2.5, PM10, SO2, NO2, O3, CO, H2S, NO and VOC.It also integrates five meteorological elements: air temperature, air humidity, wind speed, wind direction, air pressure. The system adopts modules for flexible configuration, small size, low cost, and is suitable for gridded, dense, and refined layout requirements.
