Description
SKC 222 Series Low Flow Pumps are miniature diaphragm-type pumps for
personal or area sampling of gases and vapors in air using sorbent tubes or sample
bags. These reliable lightweight pumps are motor-operated and powered by
a rechargeable batt ery pack. Featuring reliable stroke counter technology, the
pump's stroke counter indicates the number of times the pump's diaphragm
has pulsed (or stroked) during the sampling period. By multiplying this
stroke number by the volume of air per stroke, an accurate determination
of air volume can be made. SKC sample pumps have special patented
valves that close positively, ensuring zero leaks. All working parts are housed in a
sturdy, shock-resistant case with belt clip. Model 222-3 pumps provide fl ows from
50 to 200 ml/min; Model 222-4 pumps provide fl ows from 20 to 80 ml/min.
