Suitable for leak detection of lithium battery cover plates, the dual-station detection reasonably coordinates the loading and unloading and leak detection action processes, greatly improving the detection rhythm; the inert gas - helium is selected as the tracer gas, which has high safety and high molecular weight. Compared with traditional detection methods, the helium mass spectrometer leak detector has the advantages of high speed, stability, reliability and strong consistency due to its small size, high penetration and strong diffusivity.

Power battery cover.
