Leak tester for automotive gasoline tanks:


After a gasoline tank has been injected with a gas containing helium up to a specified pressure, the Helium leak tester uses mass spectrometry to measure leakage into the chamber and then determines whether that leakage is under or above a leakage threshold.


Warp Prevention Feature for Thin Tanks:


The differential pressure control feature prevents warping of the gasoline tank in the vacuum chamber.


A variety of fail safe features:

Fail safe features protect the inspection circuit if extreme tank leakage occurs.
