Vacuum leak detection

Posted on Tue, 14 Jun 2022 02:32:07 +0000

Vacuum leak detection is the process of detecting the leak location and size of the vacuum system. Air leakage is the phenomenon in which gas flows from the high pressure side to the low pressure side through leaks or gaps in the system. False leakage is a physical phenomenon relative to real lea...
