Helium Leak Detection

Applying to the leakage detection of soft-packed Lithium battery

The equipment is composed of vacuum system (combination of front stage pump and molecular pump), detection system (valve, built-in leak, helium mass spectrometer chamber) and circuit system (main board, power board, molecular pump drive board, communication board, etc.). It uses helium as the sample gas. Helium has the characteristics of small molecular weight, relatively active, small content in the air (5ppm), non-toxic and harmless.

Operating Methods:

Putting the lithium battery into the cavity

Vacuuming the cavity

Testing the leakage of the Lithium battery by filling helium into the vacuum cavity which connected with the leak detector

Characteristics:

①High Sensitivity & High Accuracy

②Strong Reliability & Safety

③Moderate Cost

④Friendly Human-machine interface
