Uniphos Gas Detector Tube

More than 200 different UNIPHOS Gas Detection Tubes are available to accurately make spot measurements for over 500 gases and vapours.

The short-term UNIPHOS Gas Detection Tubes are used with the ASP-40 Air Sampling Pump.

Gas detector tubes provide a simple measurement technique to detect toxic gas concentration in air samples. The tubes are pre-calibrated and take only a few minutes to complete sampling. The concentration is read directly from the length of color stain.

  •  Highly specific to target gas
  •  Simple device
  •  No requirement of complicated accessories
  •  No requirement of specialist to operate
  •  It is pre-calibrated and reads directly the target gas concentration
  •  Available for most of the industrial toxic gases and chemical vapours

It is useful for the air monitoring at work place & confined space in Industries like:

  •  Petrochemical & Refineries
  •  Pharmaceutical
  •  Chemical & Fertilizer
  •  Fumigation
  •  Food Industry
  •  Pulp & Paper Mills Industries
  •  Power & Steel Plants
  •  Municipal Corporations
  •  Environmental monitoring agencies and many more
