Description

DIGITEL Low Volume Samplers DPA-14 are fully automatic systems to sample dust and aerosol particles for later assessment and analysis (gravimetric and analytical determination) in accordance with EN12341:2014. The sampler 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. They are automatically changed to the flow position at the preset time. The devices can be integrated in automatic monitoring systems via various interfaces. The cabinet housing of the DIGITEL LVS DPA-14 DL is suited for 19’’ rack installation or can be installed on the floor 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.
