The secondary helium leak testing equipment for new energy power batteries is the "gatekeeper" for ensuring the safety and long lifespan of power batteries. It uses highly sensitive helium mass spectrometry leak detection technology to precisely detect extremely small leaks in critical areas such as the sealing nail at the injection port during the final stage of battery production. Its characteristics of automation, high efficiency, high precision, non-destructiveness, and traceability make it an indispensable core equipment in modern, high-quality power battery production lines. As battery technology advances and quality requirements continue to rise, secondary helium leak testing equipment is also continuously evolving towards higher efficiency, higher precision, lower cost, and greater intelligence..
