Gas Sampling Pump Features
- For further durability, the integrated tip breaker features a diamond edge that slices through the detector tube’s surface. This greatly simplifies, secures, and eases tip-breaking. For convenient and safe disposal, discarded tips are placed in a storage container.
- The handle can be pushed out with even less effort thanks to the pump piston’s reduced diameter. This makes it simple for anyone to use the pump. Furthermore, GASTEC Pump Models GV-110 and GV-100 satisfy EN1231, Workplace Atmospheres, leakage test.-Detector tube measuring systems for the short term: requirements and test procedures 4.2 Tube pump for detection, 4.2.2 Leakage “The detector tube pump with the closed detector tube connection shall be tight so that during the first minute of a pump stroke the leakage rate does not exceed 3mL/min.” A red line on the GASTEC pump shaft indicates the leakage rates.
- The pump body is covered with a soft elastomer, with the middle portion narrower than the ends to ensure a firm grip on the pump cylinder. The other outer surfaces of the pump are made of non-sparking materials of ABS resin except for the opening of the tube tip cutter, which is made of chromed stainless steel.
- 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. The attached flow finish indicator tells you automatically when the stroke is complete. When the white disk pops out, the sample is complete.
- The automatic stroke counter built-in model GV-110 (in Model GV-110S) gas sampling pump can track up to ten pump strokes automatically so there is no chance of miscounting.
