MSA Kwik-Draw Hand Sampling Pump

The Kwik-Draw pump lets you detect gases and vapors with just the squeeze of a hand. Simply place your fingers around the hand grip and push the knob in for a precise sample volume. The length or shade of the color change on the tube indicates the concentration of the gas or vapor in the air. A scale is printed on each tube for interpretation of the reading. A mechanical stroke counter shows the exact number of strokes performed and provides a positive stop when fully compressed. The end-of-stroke indicator "winks" after the precise volume is drawn to ensure enough air has sampled.
