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.
