Product Description

VAC-V1 Permeation Rate Measurement System  is based on the differential pressure method to test gas transmission rate of plastic films, composite films, high barrier materials, sheeting, metal foils, rubber, tires and permeable membranes.

The test can be performanced as follows:

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 the 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.


  • Test modes: proportional mode and standard mode
  • Test range could be extended
  • Temperature control
  • Controlled by computer 
  • Test process is automatic
