A Draeger tube is a glass tube filled with specific chemical reagents that can detect and measure the concentration of a particular gas or vapor in the air. When air is drawn through the tube, the reagents change color, allowing users to read the concentration of the target substance from a calibrated scale on the tube. Draeger tubes are commonly used for on-the-spot air quality testing in industries such as manufacturing, mining, and chemical processing.
