Ambient air sampling system PNS T-DM series

automaticcontinuous-flowfor environmental analysis

The PNS T-DM combines a low / medium volume sampler (LVS or MVS) and a filter changer in a stainless steel cabinet. It collects fine particulate matter on sampling filters according to EN 12341:2014 (PM10 and PM2.5). For this purpose, a vacuum pump draws in ambient air, and the system fractionates the airborne particles in a sampling inlet. The air containing the desired fine particulate fraction then passes through the filter, where the particles are collected and made available for subsequent gravimetric assessment or analysis. The automatic filter changer with Geneva drive and two parallel filter magazines facilitates sequential series of up to 18 or 24 sampling cycles. The volumetric flow rate is measured with an orifice plate and electronically adjusted with an accuracy of ≤ 2%.
