Operating Principle：
Designed based on the Differential Pressure Method. The pre-conditioned specimen is mounted between the high-pressure and low-pressure chambers and clamped tightly. The entire system is then evacuated (vacuumed). Test gas is introduced into the high-pressure chamber to maintain a constant pressure differential across the specimen. Driven by this gradient, the gas permeates from the high-pressure chamber through the film into the low-pressure chamber. By monitoring the pressure changes in the low-pressure chamber, the barrier parameters of the specimen are calculated.
Standards：
ISO 15105-1、ISO 2556、GB/T 1038-2000、ASTM D1434、JIS K7126-1、YBB 00082003
Application Fields：
Packaging | Food | Pharmaceuticals | New Materials | Chemical Industry | Printing
Intended Use：
Used to determine the gas transmission rate (GTR) of O2,CO2,N2 and other gases for various films and packaging materials.
Suitable for gas permeability testing of films, sheets, paper, packages, and related materials in fields such as food, pharmaceuticals, medical devices, daily chemicals, and photovoltaic electronics. It provides wide-range and high-efficiency detection for materials with high, medium, and low gas barrier properties.
