G2/131 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.

Professional Technology

• System provides proportional and standard test modes with convenient parameter settings
• The gas transmission rate as well as the coefficients of permeability, solubility and diffusion can be obtained at one operation
• 3 distinct or identical specimens can be tested simultaneously with the individual test results
• Wide test range for different materials with high, medium and low barrier properties
• Various types of gases are testable: sole gas, mixed gases, poisonous gases, explosive gases and other dangerous gases (customization is required) • World exclusive data fitting function that could easily calculate gas permeability and other parameters at different temperatures
• Top quality parts and components made by world famous brands are used to ensure reliable overall product performance • Reference film for fast calibration ensures accurate and universal test data
