Dr ger Tubes are glass vials filled with a chemical reagent that reacts to a specific chemical or family of chemicals. A calibrated 100mL sample of air is drawn through the tube with the Dr ger accuro bellows pump. If the targeted chemical is present, the reagent in the tube changes color and the length of the color change typically indicates the measured concentration. This detection system is one of the world s most popular forms of gas detection.
