Increased urbanisation has accelerated the concentration of Particulate Matter (PM) in the environment, leading to adverse health effects for populations. The Acoem HiVol 3000 particulate sampler performs remote unattended sampling of PM2.5, PM10 or TSP across urban air quality networks. It incorporates advanced programming functions and electronic volumetric flow control to maintain a consistent flow and collect a truly representative sample of particulate matter.
