Dosimeter Tubes

Dosimeter tubes are also known as long term detector tubes. They can be used for the measurement of Time Weighted Average (TWA) of target gas.

These tubes are available for Phosphine, Oxygen, Ammonia and Carbon Dioxide.


Features

  • Cost effective method
  • No sample draw pump is required

 
Specifications

For Fumigation:

Phosphine

(1-200) x 102 ppm hrs

(1-200) x 103 ppm hrs

Oxygen

(1-100) x 150 ppm hrs

Personal Safety:

Ammonia

25-500 ppm hrs

Carbon Dioxide

(5-120) x 103 ppm hrs

 

Applications

To measure (TLV-TWA) personal exposure Value

To monitor day to day gas concentration and distribution in the work place and compare with standard (TLV- TWA) values given in by the government.

To certify the adequacy of phosphine fumigation
