Helium leak detectors from agilent are designed for demanding vacuum and sniffing applications Helium leak detection technology helium leak testing is described as a means of finding leaks in different types of enclosed or sealed systems utilizing helium as a tracer gas Using helium leak detectors is one of the most accurate and fastest ways to find leaks in your vacuum system
There are 4 methods to use helium leak detectors.
A helium mass spectrometer or helium leak detector is an instrument commonly used to detect and locate small leaks It was initially developed in the manhattan project during world war ii to find extremely small leaks in the gas diffusion process of uranium enrichment plants [1] it typically uses a vacuum chamber in which a sealed container filled with helium is placed Vacuum leak detection methods leak detection with tracer gases tracer gas leak detection using helium or hydrogen forming gas (a mixture of hydrogen and an inert gas, usually nitrogen) is ideal for identifying extremely low leak rates with high precision.
Hvs leak detection provides maintenance and repairs for helium leak detectors, vacuum pumps and other vacuum related equipment We offer field service, shop service, pm contracts & equipment rebuilds. 8 methods of helium leak test do you know how many ways to test leaks (1) spray method ・to detect helium coming inside the test object by spraying helium with a spray gun after evacuating the inside of the test object
・suitable for finding a small leak point, applying to finding a relatively small leak.
