How it works


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.

Method in brief

  1. Insert a Kitagawa tube into the Kitagawa pump.
  2. Take one easy stroke of the pump.
  3. Wait for the flow indicator button to pop up and show that sampling time is complete. Read off the scale to establish the concentration of the target gas.
