Leak Testing: Guide to helium leak testing TQC Ltd

In most helium leak testing applications, one uses a mass spectrometer tuned to detect helium although it is possible to use a residual gas analyser. Helium leak testing can be generally be between one thousand and one million times more sensitive than using pressure decay techniques.

Helium Leak Testing Services | Leak Detection | ‎

Helium leak testing utilizes a Helium Leak Detector, also referred to as a Mass Spectrometer Leak Detector (MSLD), to find a leak inside or outside of a system and then measure the leak rate. The helium leaks in/out of the tested product and is measured by the detector.

Helium Leak Test Systems | Trace Gas Leak Testing Systems

For leak testing applications that have a reject leak rate too small to accurately detect with air leak testing instruments, your best choice for measurable and repeatable leak testing results is with Helium leak testing. Helium leak test instruments can detect leak rates down to 1×1010 sccs and beyond.

Helium Leak Testing | Atlantic Leak Detection

Helium Detectors are used primarily in leak detection situations where sonic detection methods are not effective (inability to maintain pressure in the line or soil saturation). Instead of “listening” for the sound of escaping gas from the leak, the Helium Detector actually detects the leaking gas itself.
