HELIUM LEAK TEST SYSTEMS

What is Helium Leak Testing?

Helium leak testing is a precise method used to identify leaks in sealed components using helium as a tracer gas. Helium is introduced into the test part, and any escaping gas is detected by a mass spectrometer, which can identify even microscopic leaks.

Why Use Helium for Leak Testing?

Helium is ideal because it’s a small, inert molecule that doesn’t react with most materials, ensuring accuracy and safety. Its low concentration in the atmosphere (around 5 ppm) makes it easy to detect even trace amounts.

Benefits of Helium Leak Testing:

1. High sensitivity (down to 1×10⁻¹² mbar.l/sec)
2. Fast and reliable
3. Non-destructive testing
4. Suitable for high-volume production

SNIFFING METHOD

The sniffing method involves pressurizing the test piece with helium gas and using a handheld sniffer probe connected to a helium leak detector.

The probe is moved over potential leak points, and if helium escapes, the detector signals a leak. This method is ideal for locating precise leak sites in complex assemblies or systems under pressure. It’s particularly useful for pinpointing leaks in production environments and maintenance inspections.

BOMBING METHOD

The bombing method involves placing a test part in a high-pressure helium atmosphere, allowing helium to penetrate any leaks.

After a set period, the part is transferred to a vacuum chamber, and any helium escaping from inside is detected by a mass spectrometer. This method is effective for detecting internal leaks in sealed components like electronic devices and hermetically sealed containers.
