How It Works

 Principle of Kitagawa Gas Detector Tubes



The Kitagawa Gas Detector Tube System consists of a pump and glass detector tubes. The tubes are filled with an absorbent material and chemical reagent which, when in the presence of the target gas, produces a colour stain along the tube.  Click on the picture below to view a video on how to use the Kitagawa Gas Detector Tube System:

A calibration scale is printed on the tube to enable the user to easily match the length of the colour stain to the concentration of the gas present.
