The Gastec GV110 Piston Pump
A Single Stroke of Genius for Sampling with Detector Tubes
- Built-in stroke counter tracks up to 10 strokes
- Handle lockable in full stroke position to draw 100 ml of air or half stroke position to draw 50 ml of air
- Flow finish indicator ensured precise sample volumes
- Contoured shape and soft elastomer-covered body for a secure, comfortable grip
- Weighs only 9.4 ounces (0.27 kg)
- Integral tube tip breaker and tip storage bin
- On-the-spot ambient temperature measurement with patented Thermal Ring
- Simple, always ready, and intrinsically safe
The Gastec® GV110 precision piston pump offers simple, accurate syringe-like technology for gas and vapor measurements. Designed for use with Gastec grab sample detector tubes, one complete stroke draws a 100-ml air sample. A flow finish indicator shows completion of full or half strokes, while the built-in stroke counter eliminates the risk of miscounting. An integral tube tip breaker and tip storage bin adds convenience. On-the-spot measurement of ambient temperature is viewed easily on the pump’s patented Thermal Ring. The GV110 pump and several boxes of tubes can be transported easily in the semi-rigid carry case with adjustable case strap that can be worn over the shoulder or secured to a belt.
Break tube tips, push in pump handle, and insert tube.
Align guides, pull out handle until locked, and wait for flow finish
indicator to pop out.
Read measurement at end of color changed layer. Mark on the tube with
pen.

One-Hand GV110 Pump Operation
The
GV700 One-hand Adapter is used with the GV110 piston-style pump to
provide convenient one-hand pump operation. The adapter uses a simple
slide valve that opens and closes at the push of a button. Closing
the valve prevents airflow into the pump and allows the user to pull
back the pump handle without taking a sample. After an open tube
has been inserted into the pump, the sample is taken by opening the
valve with another push of the button. The adapter can be left in
the open position to allow normal use of the pump. The GV700 Adapter
screws onto the pump. The tube holder screws onto the adapter. It’s
simple, accurate, and reliable just like the GV110 pump.
- To assure optimum accuracy, all detector tube hand pumps should be checked for leaks on a regular basis.
- Detector tubes are factory calibrated for a specific flow dynamic provided by a system’s pump. Always use detector tubes with the pump specified by the manufacturer. Interchanging brands of pumps and tubes can produce a significant reduction in accuracy.
- Gastec grab sample detector tubes can be used at temperatures from 32 to 104 F (0 to 40 C). For higher temperature applications, use a hot probe (see accessories).
- Do not enter closed spaces without confirming safety. When sampling in closed spaces, determine concentration remotely by using an optional extension hose or probe connected to the detector tube system (see accessories).
- Use detector tubes for screening and field surveys. Use validated methods for compliance sampling.
- For detector tube reading:
- When the end of the color change layer is flat, read the value at the end
of the layer.
- When the end of the color change layer is slanted, read the value in the middle of the slant.
- When the demarcation of the color change layer is pale, read the value in the middle between the dark layer
end and the pale layer end.
- To aid reading results:
- Hold tube against a light background.
- Compare tube against an unused tube from the same box.
