Solution for Short-Term Gas Measurement Requirements

The GASTEC detector tubes from A1-Cbiss (UK) present superior advantages in comparison to traditional electronic sampling equipment. They are cost effective, easy to use, do not require calibration and do not require further laboratory analysis. Providing fast & accurate results in the field, GASTEC tubes are ideal for spot sampling.

These versatile tubes can be utilised in countless applications, including fire fighting (HAZMAT), laboratory, environmental protection, health and safety and many other areas that require immediate exposure levels.

Over 600 GASTEC tubes are available covering a wide range of gases and measurement ranges. Most of which, offer multiple ranges that can easily be interpreted using the scale provided along the side of the tube.

The functioning principle is surprisingly simple. The GASTEC detector tubes are glass tubes that look like a test tube, filled with chemical reagents that absorb and react with the target gas / vapour being monitored. A colorimetric stain (colour change) is then created. For most tubes, the concentration is read directly from the measurement scale provided. This reaction is caused when a specified volume of ambient air (usually around 100ml) is drawn through the tube using the GASTEC piston pump. Small quantities of gas are sufficient enough to provide a reading allowing the user to quickly and easily analyse the results.

The GASTEC Pump GV-100S offers a slim, sleek and ergonomic piston-style design with a firm grip to take samples of 50ml (half-stroke) or 100ml (full-stroke). Quick and easy to use, the GV-100S only requires a few strokes, drawn easily with a handle that requires minimum effort.

Equipped with a built in tube tip breaker, flow finish indicator (provides indication when stroke is complete) and a maintenance kit, the GASTEC sampling pump provides the edge over other sampling competitors.

The 12th edition of the GASTEC handbook (HBE) provides a handy, complete overview of all available tubes. It details the gases that can be measured in alphabetical order (and synonyms), number of pump strokes required, and possible interferences. It also identifies the required colour change of the tube and full scale reading available. The GASTEC handbook is included as part of the GASTEC Starter Kit.
