- DIGITEL’s DPA14 low volume samplers are fully automatic systems for sampling dust particles and aerosols for further evaluation and analysis (gravimetric and analytical determination) in accordance with EN12341:2014.
- The operating range of the sampler in standard execution is from 5 to 50 liters per minute (0.3 to 3m3/h).
- It has a stock of 30 filters stretched in filter holders. They automatically switch to the flow position at the preset time.
- The devices can be integrated into automatic monitoring systems via various interfaces.
- The housing is suitable for outdoor installation.
- It is easy to transport and, thanks to its good sound insulation, very quiet.
- The superior finish of the sampler mechanics, supported by the most modern technical and electronic control, guarantees a long service life and absolutely reliable operation.
- An integrated microprocessor unit controls the filter changes at the 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 time for filter change is kept to a minimum, the automatic filter change is done in 2 seconds and the blower starts up again.
- 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 keeps electrical power consumption to a minimum.
- An optional self-calibration device is available for autonomous calibration of the Venturi orifice flow control.
- The mechanical components that are in contact with the measuring air are coated with an extremely smooth, corrosion-resistant surface.
- The DPA14 low-volume sampler has different interfaces for data transmission and remote control.
- The filter tanks can be filled and emptied with one hand, without the need for additional tools.
- An optional bar code reader allows direct identification of the filters in the sampler.
