Battery Pack Helium Leak Testing Machine with Sniffer Probe
The Suction Gun Helium Leak Detector is an industrial-grade leak
testing equipment designed for high-precision sealing verification
of battery packs and other airtight components. This system uses
helium injection at controlled pressure to detect microscopic leaks
through a handheld sniffer probe that precisely identifies leakage
locations.
Advanced Detection Technology
The system operates by injecting helium into test objects at
controlled pressure. Due to helium's extremely small molecule size
and chemical inertness, it escapes through even the tiniest leak
paths. When leaks exist, helium migrates outside the product
surface and is detected by the handheld sniffer probe, providing
precise leak location identification.
Key Advantages Over Conventional Methods
Compared with conventional pressure decay testing, helium leak
testing offers superior sensitivity, faster detection speeds, and
reliable quantitative results. This makes it widely adopted in
industries requiring strict sealing integrity standards.
