Gravikon sampler PM 4-2 compact stationary dust sampling system for the mobile use (license IFA)
Constant flow rate 4 m³/ h, filter diam. 70 mm
The portable, high volume dust sampling system Gravikon PM 4 has been developed by the BGIA Institute for Occupational Safety at Work, St. Augustin and is manufactured under license by GSA Messgerätebau GmbH, Neuss.
The instrument can be used for the sampling of the inhalable dust and the respirable fraction of inert dusts acc. to EN 481 as well as for the simultaneous sampling of particulates and filter passing gaseous substances (PCDD/PCDF, PCB).
Depending on the problem definition the suitable filter head is connected to the basic instrument. The sampler Gravikon PM 4 offers the possibility of an optional mains-independent operation, e.g. for the use at mobile work places, and helps to solve many measurement tasks because of its high, regulated flow rate of 4 m³/ h and the flexible and easily handled sampling heads. On one hand the relative high air throughput allows the measurement at places with low concentrations of hazardous substances, on the other hand the Gravikon PM 4 is substantially suitable for the sampling in small rooms and drivers´ cabins without influence on the concentration. One special application for instance is the use for the determination of diesel motor emissions (DME).

The basic sampler PM 4 has been completely redesigned and substantially reduced in dimensions and weight compared with the previous constructions: The basic sampler PM 4-2 is equipped with a stateof-the-art high performance turbine and is easily operated by means of the keypad. The instrument is powered either by mains via the integrated power supply unit or by an optional battery unit, which has to be connected to the sampler by means of a connecting cable with screw threads. Charging of the battery is done with an external battery charger.

The system Gravikon PM 4 consists of:
The basic instrument PM 4-2 in a metal housing with power supply and sound absorber
An external 25.9 V battery unit (optional)
The fine dust collection head for sampling of the respirable dust fraction (PM 4 F)
The adapter tube for the fine dust collection head
The total dust collection head for sampling of the inhalable dust fraction (PM 4 G)
Filter cassettes with closing cover
A height adjustable tripod for the filter heads
Basic Instrument Gravikon PM 4-2

The basic instrument generates a nearly pulsationfree air flow, which is regulated to a constant value of 4 m³/ h independent of the degree of the filter loading up to 7.5 kPa pressure drop. due to the intrgrated pressure- and temperaturecompensation variations of the atmospheric pressure because of different heights of measurement sites above sea level and meteorological conditions are compensated as well as temperature changes during sampling. An illuminated LCD display with large figures and LEDs for the display of the operating state provide an improved operating comfort. The desired run time is programmable.
