The Accuro manual gas detector pump is used for spot measurements with tubes. The Accuro gas detector pump can easily be operated with one hand, and allows reliable measurements in locations that are difficult to access. The Accuro is a bellows pump, with which the air sample is drawn through the tube using strokes. The body of the pump consists of a bellows, which is completely pushed together for the measurement. When the bellows is released, the air is drawn automatically and the gas sample to be measured is sucked through the tube being used. The sampling process is completed when the body of the pump has opened completely. The end of a stroke is indicated by a pressure-controlled display on the body of the Accuro pump.
