Helium Mass Spectrometer Leak Detection

At McVac, leak integrity is never an afterthought. Nearly every part we manufacture for vacuum or critical atmosphere applications is rigorously tested using an industry-standard Helium Mass Spectrometer Leak Detector.

In many cases, components are tested multiple times throughout the production process to ensure reliability at every stage.

Our production and test teams are highly trained in advanced helium leak detection protocols, and they understand just how critical leak-tight performance is in high-vacuum systems. That’s why every test is performed with precision, attention to detail, and full traceability — so you can be confident your parts are certified leak-free and application-ready.
