The sampling system PNS DMC is based on the technique of a low / medium volume sampler (LVS or MVS) and features an automatic filter changer. It is developed for installation within a 19-inch rack in a space-saving design.
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.
