GAS-TESTER™ II H DETECTOR TUBE PUMP

The Gas-Tester II H Pump is set for action by compressing the bellows and is the leading ATEX pump on the market. A pump stroke is started by pressing the release button. When the sample (100ml) is drawn through the tube, the end-of-stroke indicator changes color. An accurate measurement is obtained because the sample draw procedure itself is controlled only by the specifications of the pump and the flow resistance of the detector tube.
