Gas Detector Tubes

The Gas Detector Tubes measurement principle is a worldwide and long used technique.


A gas detector tube is a glass tube filled with a chemical reagent granulate, which discolours when it comes in contact with the target gas. To get an accurate reading, each tube has been calibrated on fixed samples of the target gas drawn through the tube with a 100ml manual pump, which allows a measuring scale to be printed on the tube. The further the discolouration of the reagent, the higher the gas concentration is. This makes the gas detector tubes system a non-electric-powered way of gas detection.


Benefits of Gas Detector Tubes:
  • Can be safely used in any hazardous or flammable area
  • Remains the most diverse means of detection in the world for the workplace at an affordable price
  • Detection of various gases available in extreme low as well as high ranges
  • On-spot  and precise measurements can be obtained in few minutes
  • No Calibration required
  • Portable, simple and extremely easy to use
