Description

DIGITEL High Volume Aerosol Samplers DH-77 are fully automatic systems to sample dust and aerosol particles for later assessment and analysis (gravi-metric and analytical determination). The sampler operation range is 100 to 1’500 litres per minute (6 to 90 m³/h). 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 field housing of the DIGITEL HVS DH-77 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 guarantees a long lifetime and absolutely reliable operation.
