 | VAC-V3 Gas Permeability Tester is used to measure gas (O2, N2 or CO2) transmission rate as well as solubility coefficient, diffusion coefficient, and permeability coefficient of flexible films. It is advaced with 6 test cells, which are in two groups with different accuracy. | 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. | Standards: | ISO15105-1, ISO 2556, ASTM D1434, JIS K7126-1 | Features: | - Gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of the specimen could be obtained at one operation.
- 6 distinct or equivalent specimens could be tested simultaneously with individual test results, which is the most efficient instrument so far in the market.
- 6 test cells are divided into two groups with distinct resolution to meet different test requirements, and resolution of group B is as good as 0.01Pa.
- Wide range and high precision temperature control to meet various test conditions.
- The instrument comes with two test modes: proportional mode and standard mode.
- Test range could be extended based on customer requirements to test 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 instrument is controlled by computer and test process is automatic.
- Reference film for fast calibration to ensure accurate and universal test data.
- Equipped with RS2323 port for convenient data transfer.
