Gas permeability test.
Suitable for O2, CO2, N2 and other non-toxic gas permeability testing of plastic film, composite film, high barrier material, sheet, metal foil, rubber and other materials
Instrument Principle
1.Differential pressure method
Place the pre-set sample between the high-pressure chamber and the low-pressure chamber, compress and seal, and then vacuum the high and low-pressure chambers at the same time; after vacuuming for a certain period of time and the vacuum degree drops to the required value, close the low-pressure chamber and move to the high-pressure Fill the chamber with test gas and adjust the pressure of the high-pressure chamber to maintain a constant pressure difference on both sides of the sample; the gas permeates from the high-pressure side of the sample to the low-pressure side under the action of the pressure difference; accurately measure the pressure change in the low-pressure chamber and calculate The gas permeability performance parameters of the sample.
2. Standards compliant
YBB 00082003, GB/T 1038, ASTM D1434, ISO 2556, ISO 15105-1, JIS K7126-A.
3. Technical characteristics
Imported high-precision vacuum sensors and pressure sensors, with high test accuracy;
Semiconductor cold and hot bidirectional temperature control, parallel type, high reliability;
Precision valve piping parts, thorough sealing, high-speed vacuum, thorough desorption, reducing test errors;
Sample side leakage prevention design, reducing sample installation leakage;
Precision pressure control to maintain the pressure difference between the high and low pressure chambers in a wide range;
Patented baseline technology to remove system background leakage and reduce test errors;
Intelligent automatic: power-on self-test, to avoid failure to continue testing; one-button start fully automatic execution of the test.
Data recording: Graphical, full process and full element recording, data will not be lost after power failure.
Data security: Optional ”GMP Computerized System” software module, with user management, authority management, data audit trail and other functions.
Working environment: indoor. There is no need for a constant temperature and humidity environment (reducing the use cost), and the test data is not affected by the environmental temperature and humidity.
