Th-16a multi-channel atmospheric particulate matter sampler can be used to continuously collect suspended particulates of different sizes in ambient air. The instrument can realize simultaneous and separate sampling of up to six samples It can collect TSP, PM10, PM2.5 and PM1 at the same time. It can also collect six samples of TSP, PM10, PM2.5 and PM1 at one time, and also measure various local meteorological parameters. Through real-time recording of various sampling and meteorological data, the source apportionment and dispersion analysis of particulate matter in ambient air can be carried out.
