    MSA/AUER detector tubes are a reliable method of testing for more than 120 hazardous gases and vapors. Detector tubes are flame sealed glass tubes containing treated adsorbent granules that react with a specific compound or group of compounds, causing the adsorbent to change color. A sample is collected by attaching the detector tube to a special bellows-type pump that draws a known volume of air with each stroke. After sampling, the length of adsorbent bed that has undergone the color change is measured from a scale printed on the tube, allowing direct reading of the vapor concentration – no extraction, no analysis, and no calculations are required.
    Because they are simple to use, detector tubes have been used in a broad range of applications. They are particularly useful when quick screening is required, such as in Haz-Mat Response, and in industrial situations in which specific groups of compounds are monitored regularly.
