Plastic Sheeting Oxygen Barrier Testing Machine
W-301B is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting and aluminum foils.
Professional Technology
- Gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of the specimen could be obtained at one operation.
- Wide range and high precision temperature and humidity control to meet various test conditions.
- Test range could be extended based on user requirements to test the materials with high permeability .
- Test results could be easily obtained even at extreme conditions by data fitting function, which could work at any temperature.
- The instrument could be used to test poisonous, inflammable, and explosive gases (customization required).
- The test process is automatic.
- Reference film for fast calibration to ensure accurate and universal test data.
- Standard RS232 port for convenient data transfer.
Standards :ISO 15105-2, GB/T 19789, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-2, YBB00082003
Test Principle
The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber.
