Product Overview: This instrument is an all-weather outdoor automatic monitoring terminal that can automatically monitor real-time parameters such as PM10, PM2.5, O3, SO2, CO, NO2, TVOC, as well as meteorological five parameters (temperature, humidity, atmospheric pressure, wind direction, wind speed). The particle monitoring adopts a dual channel radiation absorption method, which can achieve simultaneous monitoring of PM10 and PM2.5 concentrations compared to a single channel. The monitoring of gaseous pollutants adopts an electrochemical method. This instrument is made of steel material, with electronic compatibility grade A design, as well as IP55 dustproof and splash proof design, sturdy and durable, and can reliably work in various complex environments.
