Gastec Gas Detection System

Al Ghwasa is the factory authorized distributor for GASTEC products in the Middle East.

Gastec standard detector tubes are thin glass tubes with calibration scales printed on them.

The GASTEC standard detector tube system consists of the GV-100S pump and GV-110S gas detection tubes. The detector tube method permits a simple, quick, and economical analysis at the working site. The tubes are also very easy to store because of their long shelf life of nearly 3 years.

Engineers can read concentrations of the substances they measure. They can also analyze a wide range of gases and vapors accurately, quickly, and easily. Processors break off both ends and connect the tube to the Model GV-100S/110S Gas Sampling Pump to activate it.

Benefits of the GASTEC Standard Detector Tube System

GASTEC offers the highest quality detector tubes for analyzing airborne gases/vapors, as well as pollutants in soil and water through state-of-the-art research and development. Tubes are now available for more than 600 different gases. It’s safe, easy to handle, one-time calibration with fast response time.

Some of the features and benefits of the Standard Detector Tube System include:

Fewer pump strokes.

Faster results in a shorter time.

Certified by the Safety Equipment Institute (SEI).

Manufactured in ISO-9001 certified refinery.

Why use Gastec?

On the spot measurement and identification of gas and their levels.

No need for electricity or battery for the operation of the equipment.

Results are obtained with minimal number of pump strokes.

Gastec Tube demarcation is highly visible and can be easily viewed.

The tubes are pre-calibrated from the factory, hence avoiding the need for any calibration on site.

The pump is easy to use and easy to maintain.

Measurement Procedures

Only three steps for measurement:

Gastec Polytec Tube System

The Gastec Polytec tube system is the most effective way of identifying unknown gases present in the environment.

Polytec is favored by emergency responders all around the world,as this clever tube rapidly gives an indication of an array of gases. This in turn enables efficient decision making on how to handle the hazards present.

Each Polytec tubes have 1 to 8 reaction layers to determine multiple unknown substances in the sample simultaneously Polytec tubes offer the flexibility to detect a range of gases using a single pump.

Gastec offers 6 types of Polytec Tubes
