Helium Leak Testing is done to trace or detect leaks in metals. The molecule of helium is very small that can pass through the smallest of leaks. Since this is inert, non-flammable, non-condensable and non-toxic gas. Although hydrogen has the smallest molecule but it is not inert and can react during testing. In conducting leak detecting tests, the Helium gas is circulated through the area to be tested. Helium Leak Testing is also known as Mass Spectrometer Leak Detector (MSLD) which is a test conducted for locating and detecting the size of leaks in a system. Under this broader category, we also provide other tests, such as Condenser Tube Helium Leak Detection, Heat Exchanger Helium Leak Testing, Fugitive Emission Testing and Helium Leak Detection Service.
