Professional Technology Tests 3 equivalent specimens at one operation and exports test results in average value 2 test modes for both films and packages, accessories package are available 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 The instrument is controlled by micro-computer with LCD, menu interface and PVC operating panel, which could conveniently export test data, results and curves Test data could be automatically and safely saved by the function of power failure protection Micro-printer and standard RS232 port for convenient data output and transfer Supports Lystem™ Lab Data Sharing System for uniform management of test results and reports Test Principle The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen and the other is slowly purged by a stream of nitrogen. Due to concentration difference between the two chambers, oxygen molecules permeate through specimen into 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 outside. This test instrument conforms to the following standards: ISO 15105-2, GB/T 19789, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-2, YBB 00082003 Applications This test instrument is applicable to the determination of oxygen transmission rate of: Basic Applications Films Including plastic films, composite paper-plastic composite films, coextruded aluminized aluminum foils, aluminum foil composite films and many others Sheeting Including various sorts of engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC OX2/231 Oxygen Permeability Tester PERME®

But its fuel permeability is the most essential factor, this instrument can be used to test permeability of plastic fuel tanks Battery Plastic Shell Battery electrolyte is protected by the plastic shell from outside environment. Battery service life is directly dependent on its permeability. This instrument can be used to test oxygen transmission rate of battery plastic shell Red Wine Bottles Test oxygen transmission rate of red wine bottles Biodegradable Films The oxygen transmission rate is an essential factor that affects biodegradable film properties and further development. Soft Plastic Infusion Bottles Oxygen is the main factor that leads injection to deterioration. It will be very important to lower oxygen content of infusion bottles. Warm Paste Packages Once exposed to oxygen before usage, warm pastes will lose efficacy, they should be placed in vacuum packages. So it is necessary to test the oxygen transmission rate of warm pastes packages.
