Question about item

The air sampler SG2500ex has been developed for the sampling of gaseous and particulate matter especially in explosive atmosphere.
The range of nominal flow rate is from 50 to 2,500 ml/min, lower flow rates down to approx. 20 ml/min are possible with higher tolerance, higher flow rates up to approx. 3,000 ml/min are also possible with shorter run times and less flow resistance/back pressure, without charger.

The SG2500ex is certified according to the directive 94/9/EC (ATEX) for the operation in potentially explosive areas with the classification: II 1G Ex ia IIB T3.

The air sampler SG2500ex is equipped with a powerful rotary vane pump, which generates a nearly pulsation-free vacuum and can overcome high flow resistances. The sampler is easy to operate and covers a wide adjustable flow range from approx. 20 to 3,000 ml/min without any gap. The requirements on a constant volume flow with changing flow resistance with fault indication and automatic shut-off are fulfilled through the automatic volume flow regulation over the complete range.

For the personal measurement of noxious substances in the air at work places small, light-weight, battery-powered pumps (PAS) are used, which are connected to appropriate sampling systems for the collection of the pollutants. The system is worn by persons in whose breathing zone the concentration of hazardous substances is to be determined. For the sampling of dust, fibers and also mould fungus the combination filter head system PGP (license IFA) is utilized, for gas sampling tube holders with sorption tubes are used.

Construction and Operation:
The air sampler SG2500ex is equipped with a rotary vane pump, which is controlled and regulated by an integrated microprocessor according to the actual power demand. The automatic flow control and regulation keeps the flow rate within the nominal range constant within ± 5% of the initial set point during the sampling time.
The sampler switches off automatically when reaching the preset sampling time or, after a certain time of fault indication on the display, when the adjusted flow rate can-not kept constant inside the required tolerance range because of too high flow resistance from the filter load or too low battery voltage. The run time is stored and the reason for the switching-off is indicated on the display.
The SG2500ex is provided with an internal battery management to ensure a controlled charging of the integrated Li-Ion-battery and to indicate the approximate charging time and charging status of the battery in %. The sampling time is programmable and the actual run time as well as possible fault messages are shown on an eight-digit LCD display.
