Helium Mass Spectrometer Leak Detector

HHV 's Mass spectrometer leak detector is a complete system used for locating and measuring the size of the leak either into or out of a device or a container. In operation, this method of leak detection is initiated when the tracer gas, helium, is introduced to a test job which is connected to the HMSLD system. The helium from the test job leak travels through to system, its partial pressure is measured and results are displayed on the measurement meter. The HMSLD operating principle consists of ionizing gases in a vacuum and accelerating various ions through an electric and magnetic field. The helium ions are separated and collected and the resulting ion current is amplified and measured as a leak in m.bar litssec.
