GASTEC Detector Tubes indicate concentrations directly by way of a calibrated scale printed on the tubes. With GASTEC, Tube System we endeavour to achieve highest quality detector tubes for analysing airborne gases/vapours, as well as pollutants in soil and water through our advanced state-of-the-art research and development. Through our efforts we have acquired a solid reputation among our customers in virtually all sectors of industry, commerce and society. Tubes are now available for more than 500 different applications.
GASTEC's simple measurement technology is used in a variety of applications, such as control of health and safety, and also in various labor environments such as factories, energy plants, and worksites.

Sampling of hazardous air pollutants

It has become extremely important to have organized air quality monitoring systems in place to implement appropriate countermeasures, in addition to being able to discuss and assess the effects of the concentration levels of hazardous air pollutants and to control the various types of exhaust. We have developed and put into practical use a gas sampling pump for the monitoring of hazardous air pollutants with assistance and advice from specialists working in a variety of fields. We are not merely confined to applications of simple measurement methods such as the Detection Tube Method. Our ultimate aim is to create a wide range of high quality environmental protection products.
eg BEZENE Measuring range : 250 - 3000µg/m3 , Scale range : (250) - 3000µg/m3

Soil and water contamination

To preserve our environment, pollutants of not only air but also ground and water should be carefully investigated to take effective counter-measures. GASTEC applied detector tube systems for ground or water analysis provide accurate, easy, and economical means for a primary research of these pollutants.
eg Trichloroethane Measuring range : 0.05 - 0.3 mg/l , Scale range : 0.05 - 0.3 mg/l

Sewer system control monitor

If corrosive hydrogen sulphide is generated in a Sewer system, it makes rust in the sewer and generates odor from underground. In the worst case, the H2S gas given off damages buildings and facilities. GASTEC sewer system control monitor makes it possible for continuous monitoring of a sewer system. Continuous monitoring is provided to watch the sewer system and corrosion of sewage pipelines, and the generation source of offensive odors.

Indoor environment

We all wish to create a safe and comfortable living environment. Carbon monoxide and carbon dioxide are both colourless and odorless, and otherwise undetectable by the senses. Nevertheless, contaminated air in the environment is a source of discomfort in our daily lives. Air quality control is important at public facilities and offices where many people gather. GASTEC carbon monoxide and carbon dioxide detector , the most advanced technology of its kind, can provide quick and accurate measurement of CO and CO2 simultaneously. Employing state-of-the-art electronic technology, small, light weight and highly sensitive, it also features an easy-to-read digital display in increments as small as 0.1ppm of carbon monoxide.
Eg Carbon Monoxide Measuring range : 5 - 50 ppm , Scale range : 5 - 50 ppm

For shipping

In order to prevent an oxygen depletion or toxicity accident, or an explosion of a flammable gas, on an oil tanker or a chemical tanker, for example, it is necessary to correctly measure the concentration of oxygen and also to measure the concentration of toxic gas or flammable gas. Gastec produces detector tube type gas measuring instruments, and also extension sampling tubes of 30 m which is the optimum length for downward-facing remote measurement in tanks, for example. In addition we have a wide range of compact and lightweight measuring instruments which have excellent operability.
GASTEC's Oxygen detector can quickly and accurately measure oxygen concentrations at a variety of different work sites subject to host of complicated and varying factors.
