Gastec tubes offer accurate, effective readings of more than 500 gases and vapors. Each glass detector tube contains a reagent which reacts with a specific gas or vapor, yielding a stain that is measured against calibrations printed on the tube. The unique absorbing media produce extremely clear lines of stain demarcation for precise reading, and are stable, with a shelf-life of up to two years, depending on the application. (See below for tube selection of specific gases and vapors.) Sold in packs of 10.
