Why need helium leak detection?
1. The sealing performance requirements increased due to industry development, general leak detection method is hard to achieve the high level leak detection.
2. The pursuit of production capacity increased due to enterprise development , helium leak detection can process the high level leak detection to achieve fast production cycle .
3.Helium leak detection can be fully automatic controlled, reliability is high and the product quality is traceability.
