C106H Gas Permeability Tester
C106H Gas Permeability Tester is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheets, and metal foils at different temperatures.
Product Features
High Efficiency
- Six independent test cells with standard area, three times the number of test cells in traditional oxygen permeability testing instruments.
- Six specimens can be tested simultaneously under the same testing condition, delivering independent test result.
- Medium and low barrier materials, test time <4 hours (including vacuumize time).
- High barrier materials, test time <4 hours (including vacuumize time).
- Automatic specimen clamping saves time and effort. The clamping force is consistent, resulting in better air tightness.
The pre-conditioned specimen is mounted in the test cell as to form a sealed barrier between two chambers. The lower-pressure chamber (lower 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 (upper chamber) and a constant pressure (adjustable) difference is generated between the two chambers. The gas permeates through the specimen from higher pressure side into the lower pressure side. The gas permeability and other barrier properties of the specimen can be obtained by analyzing the pressure changes in the lower chamber.
