a few companies who were early pioneers of colorimetric gas detector tubes also known as detector tubes used to measure the concentration of gases present . in a typical colorimetric gas detector tube a known volume of air is pumped through a tube using a pump . the tube typically has a layer which indicates the analyte by changing colour depending on the amount of the gas which has passed through the tube the length of the zone which has changed colour will be different . 9 10 today colorimetric gas detector tubes are used throughout industry as a low cost and easy to use tool for detecting the presence of gases and are available from a wide range of manufacturers . an early limitation of detector tubes is that they were designed to detect a single known gas or vapor . advancements in the design and capability of detector tubes came with the introduction of such tools as the hazmat kit . the specialty kits are designed for use by hazardous material response teams in determining what gases or vapors are present . through using a stack of colorimetric material that change color based upon the presence of an organic or inorganic gas . diving equipment edit two cylinders hand
