Gas Permeability Tester
VAC-V2 Gas permeability tester is applicable to films and sheets test of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient under different temperatures.
Characteristics
Manometric principle,compatible with GB, ISO, ASTM standards.
Three independent test chambers, can display relative data, average data and statistic data.
World-famous vacuum sensor of highly precision ensuring accurate test data.
Temperature control device enables permeability test at any temperature between 5~95ºC.
World-famous brand elements with stable and reliable performance.
Optional dual test modes: Conventional and non-standard.
Super powerful software support, automatically calculating solubility, permeability and diffusion coefficients. EXCEL format conversion, graph display.
Word original design. Curvefitting Methodology for gas transmission rate, diffusion coefficient, solubility coefficient and permeability coefficient at any temperature.
Can easily get gas transmission rate, diffusion coefficient, solubility coefficient and permeability coefficient of the materials at any temperatures between -273ºC~200ºC.
Intelligent parameter setting and test operation; Automatization of the whole test process.
Super reliable performance, nonstop operation, and improved test efficiency.
Satisfactory data repeatability and small margin for personal error.
Blank test with little systematic error; General performance ranks frist among similar products in the world.
Calibration of reference film, easy and convenient to operate.
Principle
Put a preconditioned specimen between the upper chamber and the lower chamber and clamp it tightly. Firstly apply vacuum to the low-pressure chamber (lower chamber) and then the whole system. When the specified degree of vacuum is reached, shut off the lower test chamber and feed test gas of certain pressure to the upper test chamber (high pressure chamber). Ensure that a constant differential pressure (adjustable) is maintained across the specimen. Hence under the gradient of differential pressure the test gas permeates from the high-pressure side to the low-pressure side. By monitoring and measuring the pressure in the low-pressure side we can get various barrier parameters of the tested specimen.
