Real-Time Particulate Matter Air Sensor is an online monitoring product used to provide real-time and accurate detection data of outdoor ambient air pollutants. This air sensor is capable of meeting the purpose of the continuous monitoring including 24-hour average Respirable Suspended Particulates (RSP) concentration, 24-hour average Fine Suspended Particulate (FSP) concentration and 1-hour average RSP concentration. It adopts a pumping sampling method and can be equipped with a variety of high-precision air sensors according to actual conditions. The monitor is capable of detecting PM2.5 (FSP), PM10 (RSP), TSP and meteorological parameters including temperature, humidity, pressure, wind speed, wind direction with high precision and high accuracy. The air sensor can be replaced according to specific needs.
