Gas Permeability Tester for Packaging Materials

Product Features

Permeance and permeability are tested simultaneously.
Touch screen interface is more convenient to operate.
High precision and wide range of temperature to meet different test conditions （Optional）
The instrument comes with three test modes: proportional mode, standard mode and time mode

Test range could be extended based on user requirements to test materials with high permeability

Pneumatic sample clamp system assured the reliability of the test and improves sealing and avoids manual error.
The instrument is controlled by PLC control system and test process is automatic
Reference film for fast calibration to ensure accurate and universal test data
Intelligent electronic system controls the whole test automatically.
Complied with GMP users’ three-level authority.
Specialized software is used to display the real-time test, analyze, and store data.
Micro-printer and USB.

Test 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.
