Gastec Gas Sampling Pumps

The Gastec detector tube system comprises a handheld Gastec sampling pump and Gastec detector tubes.

Gastec Pump

The Gastec pump operates on a piston principle:

  • Simple, always ready, and intrinsically safe
  • 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.

Step 1

Step 1.
Break tube tips, push in pump handle, and insert tube.

Step 2

Step 2.
Align guides, pull out handle until locked, and wait for flow finish indicator to pop out.

Step 3

Step 3.
Read measurement at end of colour changed layer. Mark on the tube with pen.
