The Influence of Vacuum Degree on Gas Permeability Test with Differential Pressure Method-Labthink i-GASTRA 7100 Gas Permeability Tester

Abstract The vacuumizing time and the vacuum degree reached by the system should be paid much attention when performing gas transmission tests with vacuum method. The vacuum degree would be reduced if the vacuumizing time is not sufficient, which would cause inaccuracy of the test results. Gas permeability of the materials is mainly tested with differential pressure method or equal pressure...
