Identify and measure specific gases with the sampling pump and gas tubes.

• Ergonomically designed sure-grip shape, lightweight and corrosion resistant
• Built-in tube tip breaker makes tip breaking easy, safe, and convenient
• Integral flow-finish indicator lets you know when sampling is complete

Use the specially designed manual pump to draw a precise 100 ml air sample through a gas analyser tube.

The resulting length-of-stain colour change can be read directly off the tube's calibration scale, yielding an accurate concentration.

Crystal clear gas tubes, distinct colour changes, and easy to read calibration scale for accurate direct-reading measurements.
