  • Low maintenance cost
  • Low noise
  • Easy programming with touchscreen
  • Easy bottle handling

Description

The DIGITEL DRA-12 is a microprocessor controlled automatic sampler for the sampling of wet depositions (rain, snow) for later assessment and analysis in the laboratory.  The device is mounted in an air-conditioned compact field housing. The collection funnel has a surface of 500 cm² (d = 252 mm). The Digitel DRA-12 is easy to transport and energy efficient because of a good insulation paired with a compressor cooler. Superior workmanship in sampler mechanics backed by the latest technical and electronic control guarantee a long lifetime and absolutely reliable operation.
