PERME VAC-V1

PERME VAC-V1 Gas Permeability Tester is applicable in the
measurement of gas permeability rate, solubility coefficient,
diffusion coefficient and permeability coefficient at various
temperature of plastic films, laminated films, high barrier material,
sheets, foils and rubber, including breathable film and tyre seal
performance, etc.

Characteristics
Computer control, full automatic testing;
Diffusion coefficient, solubility coefficient and permeability coefficient
measurement.
Two testing modes of proportional and non-proportional;
Measure range can be extended by software.
Data curvefitting function at any temperatures;
Can be extended to cover the tests for poisonous and explosive gases;
Rapid calibration with reference film;
Temperature and humidity testing port;
RS232 interface;
Network transmission interface for LAN data management and Internet data transmission.

Principle
Put the pre-conditioned specimen between the upper chamber and chamber, clamp it tightly. First vacuumize the low-pressure
chamber (lower chamber), and then the whole system. When the specified degree of vacuum is achieved, shut off the lower test
chamber and feed test gas to the upper test chamber (high pressure chamber) until certain pressure is reached. Ensure that a
constant differential pressure (adjustable) is maintained across the specimen. Hence under the gradient of differential pressure the
test gas permeates from the high-pressure side to the low-pressure side. By monitoring and measuring the pressure in the
low-pressure side we can get various barrier parameters of the tested specimen.
