53708 Gas Detector Tube Pump
Gas Sampling Pumps are available with options for every use and budget. You can choose a pump with or without a counter to automatically track strokes for applications requiring multiple pump strokes. You can also choose a pump with or without a one-hand adapter to convert the pump to convenient one-button/one-hand operation for those tough-to-reach spots. Pumps are intrinsically safe, pre-calibrated, and include a lifetime warranty.
Diamond Tube-Tip Breaker
The built-in tip breaker incorporates a diamond edge that cuts the surface of the detector tube. This makes the tip breaking much easier, safer and convenient.
The pump piston has been designed with a smaller diameter so that the handle can be pulled out with even less effort. The pump body is covered with a soft elastomer, The pump is make of non-sparking materials of ABS resin.
The full-stroke (100ml) and the half-stroke(50ml) positions are marked exactly by the red line on the pump shaft, and the handle is precisely locked at those positions.
Improved Flow Finish Indicator
The attached flow finish indicator tells you automatically when the stroke is complete. When the white disk pops out, the sample is complete.
