The new PNA 3000 sampler guarantees reliable sampling for measuring harmful substances in the air (e.g. asbestos, mineral fibres, PCB, etc.). This device is designed for measurements both inside and outside as well as emissions measurements in accordance with VDI 3861 Bl. 2. The exterior design and operation is identical to that of the PNA 384 sampler. However, the PNA 3000 is designed for higher air flow rates up to 30 litres/min. The volume flow is controlled automatically via an electronic connection on the integrated, calibrated gas meter, which means that the suction power of the PNA 3000 can be set directly. No other devices (e.g. flow meters) are required for the operation of the PNA 3000.
