High Volume Aerosol Sampler DHA-80
High Volume Aerosol Sampler DHA-80 with automatic filter changer for autonomous, continuous sampling
Description
DIGITEL High Volume Samplers DHA-80 are fully automatic systems to sample dust and aerosol particles for later assessment and analysis (gravimetric and analytical determination). The sampler operation range in standard execution is 100 to 1’500 litres per minute (6 to 90 m³/h). The DIGITEL HVS DHA-80 has a magazine of 15 filters stretched in filter holders. They are automatically changed to the flow position at the preset time. The sampling can be programmed with starting time and duration but also for more complex applications using cycles for interrupted sampling or wind dependant sampling (with optional wind sensor). The devices can be integrated in automatic monitoring systems via various interfaces. The field housing of the DIGITEL HVS DHA-80 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 electronic control guarantee a long lifetime and absolutely reliable operation.
