Test Principle

The pre-conditioned specimen is mounted in the test cell as to form a sealed barrier between two chambers. The lower-pressure chamber (lower 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 (upper chamber) and a constant pressure (adjustable) difference is generated between the two chambers. The gas permeates through the specimen from higher pressure side into the lower pressure side. The gas permeability of the specimen can be obtained by analyzing the pressure changes in the lower chamber.

Advanced Barrier Property Analysis

This instrument offers robust, repeatable testing for complex film structures, utilizing a high-sensitivity coulometric sensor to detect and quantify barrier performance. Automated gas flow regulation and optimized environmental control allow for highly accurate and consistent measurements, ensuring each result meets industrial and research standards. Data storage capabilities support traceability and multi-group statistics, while the intuitive microcomputer touch interface streamlines workflow for both routine and detailed studies.


Efficient Operation and User Comfort

Engineered for laboratory convenience, the instrument combines an LCD touchscreen, ergonomic table-top design, and user management features for simplified control and data access. Automated calibration and protection against overload and leakage prioritize safety and ease. With simultaneous testing of up to three specimens and fast response times (30 seconds), productivity is maximized without compromising precision.
