G2/131 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 aluminum foils at different temperatures. The system is equipped with three diffusion cells, which could test specimens simultaneously with individual test results. The testing process conforms to GB, ISO, ASTM and other international standards.
G2/131 utilizes Labthink’s latest embedded computer control system that provides a better performance than traditional single chip system.
The instrument is equipped with Labthink’s latest intelligent operating software, with user-friendly operating interface and intelligent data management. It also supports LystemTM Lab Data Sharing System, which ensures uniform management of test results and test reports.
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 the two chambers. The gas permeates through the specimen from 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.
This test instrument conforms to the following standards:
ISO 2556, ISO 15105-1, GB/T 1038-2000, ASTM D1434, JIS K7126-1, YBB 00082003
This instrument is applicable to the determination of gas permeability of:
