Description
The Drager-Tubes are an extremely cost effective and, above all, precise method of short term gas measurement. The Drager Tube, a sealed glass vial, contains on a solid carrier material a chemical reagent which reacts to a particular gas or vapor with a characteristic colour change. To cause this reaction, a defined volume of ambient air is drawn through the tube using a gas detector pump. Even small quantities of gas are sufficient, and the user can easily read and analyse the result because of the scale marks printed on the tube.
