Description

The DIGITEL Low Volume Sampler (LVS) DPA-14 Double Line (DL) is a fully automatic system to sample dust and aerosol particles for later assessment and analysis (gravimetric and analytical determination) in accordance with EN12341. It features two completely independent sampling lines with automatic filter changers for parallel sampling of PM10 and PM2.5 inlets.  The sampler’s operation range in standard execution is 15 to 50 litres per minute (0.9 to 3m³/h). The DIGITEL LVS DPA-14 DL has two magazines of 30 filters each stretched in filter holders for up to 4 weeks of daily sampling of PM10 and PM2.5 samples. They are automatically changed to the flow position at the preset time.  The cabinet housing of the DIGITEL LVS DPA-14 DL is suited for 19’’ rack installation or can be installed on the floor or on a table in a measurement station. An additional noise baffler allows extremely silent operation. Superior workmanship in sampler mechanics backed by the latest technical and electronic control guarantee a long lifetime and absolutely reliable operation.
