Differential pressure gas transmission rate tester features

1. The gas permeability, solubility coefficient, diffusion coefficient and permeability coefficient of the sample can be simultaneously measured;

2. The three test chambers are completely independent and can test three identical or different samples simultaneously;

3. Wide range, high precision temperature and humidity control, can meet the gas penetration test under a variety of test conditions;

4. The test range can be expanded as needed to meet the requirements of large transmittance tests;

5. Wide range of temperature data fitting for easy access to test results under extreme temperature conditions;

6. Suitable for permeability testing of a variety of gases, such as oxygen, carbon dioxide, nitrogen, air, helium, etc. (flammable and explosive gases can be customized);

7.The system is controlled by computer and the whole test process is completed automatically;

8. The vacuum pump automatically starts and stops according to the progress of the experiment, without manual operation;

9. Provide standard film for rapid calibration to ensure the accuracy and versatility of the test data;

10. Equipped with RS232 universal data interface for easy data transfer.

Standard: ASTM D1434, ISO 2556, ISO 15105-1
