Dissolved substances in a solution can be measured by immersing the Gastec Dissolved Substance/Solution Detector Tube (with both ends broken) into a solution. When the detector tube is immersed vertically, with the arrow pointing upward, the solution will rise up through the tube. An indication is then noted on the tube.
