VAC-V3 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.
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 high permeability
Test results could be easily obtained even at extreme conditions by data fitting function, which could work at any temperature
The instrument could be used to test poisonous, inflammable and explosive gases (customization required)
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, and resolution of group B is as good as 0.01Pa
Wide range and high precision temperature control to meet various test conditions
The instrument is controlled by computer and test process is automatic
Reference film for fast calibration to ensure accurate and universal test data
Equipped with RS2323 port for convenient data transfer
