PAS-500 Micro Air Sampler

This low flow pump is lightweight (4 ounces) and compact (7 inches high), fitting easily into a shirt pocket. The adsorbent tube connects directly to the inlet of the pump. The micro air sampler is versatile, adapts to fit both 6mm and 8mm tubes and the flow range is 40-200 cc/min. The low flow adapter enables sampling at 20 cc/min.
The unit is powered by a 9-volt battery. The full flow regulation feature provides constant voltage to the pump, even as battery voltage drops. It is intrinsically safe - a built in resistor limits the power current, preventing any short circuit.
