MBr Gas Detector Tubes

Gas Detector tubes, also known as colorimetric gas detection tubes, are sealed glass tubes filled with a sensing chemical. When air from inside or outside the fumigated space is drawn through the tube using the appropriate gas sampling pump, the sensing chemical inside changes color and forms a stain. The length of the stain thus formed is proportional to the gas concentration present at the point of sampling and can be easily read from the scale printed on the tube.  

Detector tubes enable the user to easily make spot measurements of Methyl Bromide in the fumigated area. MBr Tubes are available in the lower concentration levels of 1 ppm. 

We offer a choice of both thick and thin tubes (KwikDraw and Uniphos) within our portfolio. 

  • Can be used to detect leaks from the fumigated structure and hence aids in personal safety and protection. 
  • Wide Range 
  • Maintenance Free 
  • Pre-Calibrated Tubes 
  • Cost Effective 
  • Easy to carry 
  • Uniphos Gas Detector Tubes to be used with ASP-40 air sampling pump  
  • KwikDraw Detector Tubes to be used with the KwikDraw Deluxe Pump
