Helium leak detection finds leaks far smaller than a bubble test or pressure-decay test can, by spraying or sniffing helium and measuring it with a mass spectrometer. It is used to test vacuum chambers, heat exchangers, HVAC and refrigeration components, gas lines, battery and electronics enclosures, and many other sealed parts. Residual gas analyzers show what gases are present inside a vacuum system, which helps track down contamination and leaks.

Frequently asked questions
Do you supply Leybold leak detectors in the UAE?
Yes. Viyon represents Leybold in the UAE and supplies helium leak detectors, residual gas analyzers and vacuum pumps.
Vacuum or sniffer leak testing: which do I need?
Vacuum (spray) testing is the most sensitive and suits parts that can be evacuated. Sniffer testing suits parts filled with helium under pressure. Describe your parts and we will advise.
Do you supply vacuum pumps as well?
Yes. We supply the Leybold range of rotary vane, dry, Roots and turbomolecular pumps.
