Machinist Inc. now offers Helium Leak Testing Machinists Inc

DHU Helium Leak Testing Helium leak testing is performed as a final non-destructive test to insure no contaminants can penetrate the unit during use. Helium is introduced into a barrier outside the unit while it is under extreme vacuum. The leak testing machine then tests for any helium gases inside the unit to determine if it is sealed.
