LVS / MVS : Low Volume / Medium Volume Sampler
The low and medium volume samplers LVS and MVS collect 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 sampler fractionates the airborne fine 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 volumetric flow rate is measured with an orifice plate and electronically adjusted with an accuracy of ≤ 2%.
