The Gastec precision pumps for use with all standard Gastec tubes can be used to monitor up to 600 gases and vapours.
Choose from the GV-100 Precision Pump and the GV-110 model which has a built in stroke counter for simple counting of the number of strokes applied. Pumps also feature a flow finish indicator to show when the stroke is complete.
The full stroke (100ml) and half stroke (50ml) positions are marked exactly by the red line on the pump shaft, and the handle is precisely locked at those positions to ensure accuracy.
Both models are supplied with a maintenance kit, instructions for use and a carrying pouch.
The pumps feature a handy tip breaker to open Gastec sampling tubes quickly and easily and are non-sparking in design.
