Gas Permeation and Barrier Test instrument VAC-V3 - 1

PERME® VAC-V3 Gas Permeability Tester VAC-V3 Gas Permeability Tester is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate as well as solubility coefficient, diffusion coefficient, and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, and aluminum foils. Professional Technology Gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of the specimen could be obtained at one operation 6 distinct or equivalent specimens could be tested simultaneously with individual test results, which is the most efficient instrument so far in the market 6 test cells are divided into two groups with distinct resolution to meet different test requirements, where resolution of group B is as good as 0.01Pa Wide range and high precision temperature control to meet various test conditions The instrument comes with two test modes: proportional mode and standard mode Test range could be extended based on customer requirements to test materials with
