Product catalog summary
Overview: The PERME® DM2/330 is a gas permeability tester designed for films and packages, utilizing both differential and equal pressure methods. It measures gas transmission rate, solubility, diffusion, and permeability coefficients for various materials including plastic, rubber, paper, glass, and metal.
Professional Technology: The device combines differential and equal pressure methods, allowing for distinct testing requirements. It can test three specimens simultaneously, providing six independent results. It features automatic temperature and humidity control, data fitting for extreme conditions, and supports testing of hazardous gases with customization.
Test Principle: The tester uses a unique patent design to perform tests using both methods. The equal pressure method involves clamping the specimen between chambers with different gases on each side, while the differential method involves creating a pressure gradient across the specimen.
Standards Compliance: The instrument complies with standards such as ISO 15105-1, ASTM D3985, and others, ensuring reliable and standardized testing results.
Applications: The tester is applicable to a wide range of materials including films, sheets, packages, and extended applications like solar back-sheets, fuel tanks, and contact lenses. It can test various gases including O2, CO2, and helium.
Technical Specifications: The equal pressure method has a test range of 0.01 to 5000 cm3/m2·d, while the differential method ranges from 0.05 to 50000 cm3/m2·24h·0.1 MPa. The instrument operates within a temperature range of 5℃ to 95℃ with high precision.
Configurations: Standard configurations include the mainframe, temperature controller, and professional software. Optional parts are available for specific testing needs.
Notes: Users must prepare gas supply and distilled water. The instrument requires specific tubing for gas connections.

molecule passes through the film into the high pure nitrogen of another side (lower chamber), and is taken to the sensor by the flowing nitrogen. By analyzing the concentration of oxygen detected by the sensor, the oxygen transmission rate and other parameters can be obtained. As to packages, nitrogen flows in the container, air or high pure oxygen fills the outside of the container. 2. Differential Method: Clamp the pre-conditioned specimen between the upper chamber and the lower chamber. Evacuate the low-pressure chamber (lower chamber) and then the whole system. When the specified degree of...
