Methods of Helium Leak Detection:
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. If quantification of the total leakage of the test object is required, a hood method is more suitable.
2. Sniffer Method:
To detect helium coming outside through a leak point by sniffing with a sniffer probe that is connected to LD, after pressurizing of the test object.
3. Vacuum Hood Method:
To detect helium coming inside the test object after evacuating the inside of the test object, hooding the outside of the test object and filling helium gas in the hood.
