G2/132 Gas Permeation and Barrier Testing Instrument is based on the differential pressure method and is professionally applicable to the determination of gas permeability of film specimens. It is equipped with three diffusion cells, which could generate test results of three equivalent specimens at one operation.

Patent design of three diffusion cells integrated in one instrument for individual or multiple tests

3 equivalent specimens can be tested simultaneously with the average value as test result

Wide test range for different materials with high, medium and low barrier properties

Various types of gases are testable: sole gas, mixed gases, poisonous gases, explosive gases and other dangerous gas

Major components are imported from renowned countries with stable and reliable performance

Wide range and high precision of automatic temperature and humidity control to support various combinations of non-standard test conditions
