Introduction of Helium Leak Detector:
Helium leak detection technology is a highly sensitive method used for detecting leaks in an enclosed system. Helium is used as a tracer gas as it is inert, non-condensable, non-flammable, and harmless. Because of its small atomic size, helium passes easily through the leaks. Helium leak detection technology provides detection of the smallest leaks and is good for outside/in and inside/out leak detection. In outside/in helium leak detection, vacuum is pulled on the container to be leak checked or vacuum is pulled through the part. Helium is sprayed in very small amounts on the suspected leak areas of the part and the vacuum pulls it through if there is a leak. The helium leak detector can then detect and quantify the helium coming through and provide the signal and display the leak rate.
