PH3 Gas Detector Tubes

Enquiry Now

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 on the spot measurements of Phosphine in the fumigated area. PH3 Tubes are available both in the lower concentration levels of 0.01 ppm, as well as the fumigation concentration levels of 400 to 5000 ppm.

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

  • Lower concentration Phosphine detector can be used to detect leaks and hence aids in personal safety and protection.
  • Higher concentration Phosphine detector tubes can be used for Process control measurement.
  • Maintenance Free
  • 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
