Gastec Gas Sampling Pumps
The Gastec detector tube system comprises a handheld Gastec sampling pump and Gastec detector tubes.
The Gastec pump operates on a piston principle:
- Simple and always ready to use
- 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 ensures precise sample volumes
- Contoured shape and soft elastomer-covered body for a secure, comfortable grip
- Weighs only 270 g
- Integral tube tip breaker and tip storage bin
The gas sampling pump is also available with a counter, which will count the number of samples taken (up to a maximum of 10), eliminating the risk of miscounting.
