FAQs

1. What is the purpose of this Gas Permeability Tester?

Gas Permeability Tester is designed to measure the oxygen transmission rate of various materials such as films, sheets, paper, and packaging. By determining the oxygen permeability, it helps evaluate the barrier properties of materials used in food packaging, pharmaceuticals, and industrial applications. This ensures that packaging materials provide adequate protection against oxygen exposure, which can affect product quality, shelf life, and safety.

2. How does this Gas Permeability Tester work?

Gas Permeability Tester operates on the Coulomb energy oxygen sensor principle, utilizing an electrochemical reaction to measure oxygen permeability. A sample is placed between two chambers—one filled with high-purity oxygen and the other with high-purity nitrogen. Oxygen molecules diffuse through the sample and are carried by nitrogen gas to an electrochemical sensor. The sensor detects the oxygen concentration based on the current generated by the reaction, which is then used to calculate the oxygen transmission rate using Faraday’s laws of electrolysis.

3. What materials can be tested with this Gas Permeability Tester?

This Gas Permeability Tester is designed to measure the oxygen permeability of a wide range of materials. It is suitable for testing plastic films, aluminum foils, laminated films, paper-based packaging, and multi-layer barrier materials. With additional accessories, it can also be used to test bottles, bowls, and other rigid packaging containers. This flexibility makes it ideal for industries such as food packaging, medical device manufacturing, and electronics, where material barrier performance is crucial.

4. Does the Gas Permeability Tester provide automated testing?

Yes, our Gas Permeability Tester features an intelligent operating system that supports automatic test modes, real-time monitoring, and data tracking. The system continuously records temperature, humidity, and gas flow, ensuring accurate and repeatable test results. It also includes an audit tracking function for quality control and regulatory compliance, allowing multi-level user authorization to prevent unauthorized access or data modification. These automation features improve efficiency, reduce human error, and enhance testing accuracy.

5. How does the Gas Permeability Tester output data?

This Gas Permeability Tester supports multiple data output formats, enabling electronic report generation, data storage, and online submission. It provides customizable test reports, allowing users to select relevant data fields for documentation. The system also supports electronic signatures and audit trails, ensuring compliance with industry regulations such as those in the pharmaceutical and food industries.
