<br />
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.<br />

Gas permeability of the materials is mainly tested with differential pressure method or equal pressure method, of which the former one is the most widely used and the most ...This story is related to the following:Sensors, Monitors and TransducersSearch for suppliers of: Vacuum Testers
