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.
Features:
- Patent design of three diffusion cells integrated in one instrument with higher test precision and lower space occupancy rate.
- 3 distinct or equivalent specimens can be tested simultaneously with the individual test results.
- The gas transmission rate as well as the coefficients of permeability, solubility and diffusion can be obtained at one operation.
- 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 gas(customization is required).
- World exclusive data fitting function that could easily calculate gas permeability and other parameters at different temperature.
- Major components are imported from renowned countries with stable and reliable performance.
- Convenient fast-access calibration port for temperature and humidity.
- Reference film for fast calibration ensures accurate and universal test data.
- Equipped with standard RS232 port for convenient data transfer.
