About

About Gastec International Corporation Gastec is the premium manufacturer of the Gas Detector Tube System - an economical, easy-to-use, and relatively precise means of on-the-spot sampling for detecting and measuring gases and vapors for up to 350 different types. We have been in business for over 50 years and our products are sold worldwide catering to various industries such as manufacturing, transportation, R&D, quality control, and winemaking among others. The Gastec Gas Detector Tube System consists of a piston-styled Gas sampling pump and various Detector tubes. By viewing the level of the color change resulting from the chemical reaction in the glass detector tube, measurements of the sample may be determined. There are also Detector tubes for dissolved substances in solutions, passive Dosi-tubes, and the Smoke Tester Kit to test air flow. In addition we have electronic devices such as our Hydrogen Sulfide Data Logger with 5 measuring ranges and the Automatic Air Sampling Pump to check for indoor air quality.
