Plastic Bags Oxygen Permeability Testing Instrument
Product Code : OX2/231
Brand Name : Labthink
Product Description
OX2/231 Oxygen Permeability Tester utilizes the coulometric sensor method to test the oxygen transmission rate of flexible films, sheets, foils and packages. It can test 3 specimens in one operation with average results.

Principle:

The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, and oxygen flows outside.

Standards:

ISO 15105-2, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-2

Features:

  • Tests 3 equivalent specimens at one operation and exports test results in average value.
  • 2 test modes for both films and packages, and accessories for package test are available for customization.
  • Equipped with constant temperature and humidity control devices (optional parts) to meet different test requirements.
  • Reference film for fast calibration to ensure accurate and universal test data.
  • Test data could be automatically and safely saved by the function of power failure protection.
  • The instrument is controlled by micro-computer with LCD, menu interface and PVC operating panel, which could conveniently export test data, test results and test curves.
