Features
- DIGITEL’s DHA-80 high volume samplers are fully automatic systems for sampling dust particles and aerosols for further evaluation and analysis (gravimetric and analytical determination).
- The operating range of the sampler in standard construction is 100 to 1,000 liters per minute (6 to 60 m3/h).
- The DIGITEL HVS DHA-80 has a store of 15 filters fixed in filter holders. They automatically rotate to the flow position at the preset time.
- Filter diameter 47 mm.
- The devices can be integrated into automatic monitoring systems via various interfaces.
- The housing is suitable for outdoor installation.
- The device is easy to transport and, thanks to its good sound insulation, very quiet.
- The superior workmanship of the sampler mechanics, supported by state-of-the-art technical and electronic control, guarantees a long service life and absolutely reliable operation.
- An integrated microprocessor unit controls the rotation of the filter at the exact preset time and collects all relevant data and events.
- The states “work” and “pause” (filter change) can be programmed with a resolution of one minute.
- The constant flow of sampled air through the filter is dynamically controlled, so that this value is maintained with good reproducibility and long-term stability that minimizes electrical power consumption.
- The blower unit is maintenance-free and guarantees a long service life (MTBF > 36,000 hours). All mechanical components of the rotating drives, as well as the units required for measurement, are provided with a highly corrosion-resistant and smooth “Ematal” coating.
- Due to the large filtering surface, a low flow velocity is produced. In addition, the homogeneous loading of dust and aerosol particles on the filter allows segmentation for different analyses.
- Different interfaces are available for data transmission and remote control.
