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. The sampler operation range in standard execution is 15 to 50 litres per minute (0.3 to 3m³/h). The DIGITEL LVS DPA-14 has a magazine of 30 filters stretched in filter holders. They are automatically changed to the flow position at the pre-set time. The devices can be integrated in automatic monitoring systems via various interfaces. The field housing of the DIGITEL LVS DPA-14 is suited for outdoor installation. It is easy to transport and because of a good sound insulation very quiet. Superior workmanship in sampler mechanics backed by the latest technical and electronic control guarantee a long lifetime and absolutely reliable operation.
