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.
