Modular Lithium Battery Helium Mass Spectrometer Leak Detector

This equipment is the first-generation ANHMS-1000 series modular helium mass spectrometer leak detector. It is compatible with both vacuum and suction gun testing methods. Its compact size allows for easy integration into automated helium testing equipment for lithium battery cells.

By monitoring the helium content at the inlet module location in real time, it can quantitatively measure the helium leakage rate of lithium battery cells. It can quickly screen out unqualified and suspicious cells whose leakage rate exceeds the set value due to reasons such as casing welding defects, injection hole welding failures, and material defects.

The ANHMS-1000 series helium mass spectrometer leak detector is widely used in primary helium testing, secondary helium testing, and battery pack airtightness testing during cell production. It can ensure that the welding quality of the casing and sealing pins, as well as the overall sealing performance of the PACK and module, meet production requirements.

• High Leak Detection Accuracy: Minimum detectable leak rate reaches 5.0E-10Pa.m³/s in vacuum mode
• High Response Speed: Response time to leakage is less than 1s, and the leakage peak can be measured within 5s
• High Stability: Yttrium-iridium oxide wire, automatically switching in case of failure; dual-channel design ensures continuous and stable operation
• Data Storage: Locally stores test data and waveforms, and supports export to USB flash drive
• Ease of Use: Compact size, rich interfaces, and simple operation, suitable for automated lithium battery helium detection equipment
