The HiVol 3000 particulate sampler performs remote unattended sampling of PM2.5, PM10 or TSP along with basic meteorological parameters. The HiVol 3000 incorporates advanced programming functions and electronic volumetric flow control to maintain a consistent flow and collect a truly representative sample of particulate matter. Optional attachments allow the sampler to measure wind speed and direction which can then be used to trigger sector selectable sampling (e.g. fence-line monitoring).
