C130H Gas Permeability Tester

C130H Gas Permeability Tester
C130H Gas Permeability Tester is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheets, and metal foils at different temperatures.

Product Features
Innovative structure design & upgraded automatic operation

• Test cells with brand new pop-up drawer type design
• Automatic specimen clamping with uniform force
• Components are supplied by global well-known manufacturers, which are reliable and stable in performance
• Intelligent test mode, one-button test operation (test temperature should be set in advance) and automatic stop
• Scientific research mode provides more flexible parameter and function settings for analysis of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient

Test Principle
     C130H is designed in accordance with differential pressure method. The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure 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 and a constant pressure 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 and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber.
