PERME® VAC-V1 (EX) Gas Permeability Tester VAC-V1 (EX) Gas Permeability Tester is based on the differential-pressure method, and is professionally applicable to the determination of gas transmission rate of common gases as well as toxic, flammable or explosive gases. VAC-V1 (EX) is suitable for the determination of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting and foils at varied temperatures. • The tester adopts Labthink's latest split control design, and complete separation between the mainframe and its control module is realized to ensure testing safety. • It is suitable for the gas permeability tests of flammable, explosive or toxic gases. • Gas transmission rate, permeability coefficient, solubility coefficient and diffusion coefficient can be determined simultaneously. • Wide-range and high-precision liquid circulation temperature controller satisfies tests under different test conditions. • Dual test process judgement modes are available: Proportional Mode and Fuzzy Mode. • The test range could be extended based on needs to satisfy testing requirements for high permeability materials. • Data fitting at any temperatures can be performed, and test results of extreme conditions could be easily obtained. • PC-controlled, and the testing process can be accomplished automatically. • Reference film is available for rapid calibration to ensure accuracy and versatility of test data. • RS232 universal data port is equipped for convenient data transfer. • The Tester is compatible with Lystem™ Lab Data Sharing System for uniform management of test results and test reports. VAC-V1 (EX) Gas Permeability Tester is designed based on the differential-pressure method. The preconditioned sample is mounted in between the upper testing chamber and lower testing chamber and clamped. First, the lower-pressure chamber (i.e., lower testing chamber) is evacuated, followed by the evacuation of the entire system. When the desired vacuum degree is reached, close the lower testing chamber and test gas of a certain pressure is flushed to the higher Labthink Instruments Co., Ltd.

pressure chamber (upper testing chamber), and a constant pressure difference (adjustable) is formed between the two chambers. The gas permeates through the sample from the high pressure side into the low pressure side due to pressure gradient. The gas permeability properties of the sample can be obtained by monitoring the pressure changes in the lower pressure chamber. The tester conforms to multiple national and international standards: ISO 15105-1, ISO 2556, GB/T 1038-2000, ASTM D1434, JIS K7126-1 and YBB 00082003.
