Gastec Corporation
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.
Gastec in operation
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:
GHS-8AT-EX
The GHS-8AT-EX is a simple continuous H2S measurement system that is easy to operate with minimal supervision in the sewer lines.
The unit checks the content of H2S in sewer systems over a period of time according to the customer’s requirement.
The unit is protected with IP66/67 enclosure deeming it fit to be used in harsh conditions without affecting its operations.
GV100 / 110S - Pump
Al Ghwasa is the factory authorized distributor for GASTEC in the process industry in the Middle East and North Africa Region.
Applications
The GV 100 / 110S pump allows measurements to be performed efficiently and easily. Each product is tested and calibrated for quality control and excellent long-term stability.
This makes it ideal for the following applications:
Shipping
Oil and gas
Sewage system control monitor
Storage tanks
Science teaching equipment
Education kits for school
Firefighting
Gastec Products & Accessories
GV-100S/GV 110S with flow finish indicator
For GV110S a counter is integrated within the industrial pump for an easier process.
The pump is made of HDPE plastic. Therefore, it will not react with the surrounding environment nor be affected by heat or pressure, it’s strong but light and doesn’t require any maintenance.

Gastec Compressed Air Quality Measurement Kit CG-1
Gastec developed a measurement system that can simply, quickly, and simultaneously measure 4 kinds of harmful contaminants (CO, CO2, Water vapour, and Oil mist) contained in compressed breathing air (cylinder or compressor).
This measurement system enables users to achieve high efficiency in the measurement by simply connecting 4 kinds of Airtec tubes to the device simultaneously.
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
