VAC-V2 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
  • 3 distinct or equivalent specimens could be tested individually with independent test results at one operation
  • Wide range and high precision temperature and humidity 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 user requirements to test the 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)
  • The instrument is controlled by computer and test process is automatic
  • Reference film for fast calibration to ensure accurate and universal test data
  • Standard RS232 port for convenient data transfer
  • Supports LystemTM Lab Data Sharing System for uniform management of test results and test reports

Test Principle

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 two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber.

This test instrument conforms to the following standards: ISO 15105-1, ISO 2556, GB/T 1038-2000, ASTM D1434, JIS K7126-1, YBB 00082003
