Helium or Hydrogen/Nitrogen Mix is injected under pressure into the unit under test (UUT). An integrated leak detector senses the presence of any gas leaking out of the UUT and measures the corresponding leak rate. This test can be performed either in manual or automatic mode.

In order not to contaminate the working environment with large quantities of tracer gas, this test follows a prior Pressure Leak Test aimed to detecting gross leaks.
