CleanAir Europe offers the COMDE DERENDA LVS 3.1 low volume sampler for rental which collects fine particles on sampling filters in accordance with EN 12341: 2014 (PM 10 and PM 2.5). To this end, a vacuum pump draws in ambient air and the sampler breaks down the fine particles suspended in the air in a sampling outlet. The air containing the fine particle fraction then passes through the filter, where the particles are collected and made available for subsequent gravimetric evaluation or analysis. The volumetric flow is measured with an orifice plate and electronically adjusted with an accuracy of ≤ 2%.
