Electrolyte Sniffer Leak Detector – BES4000

INFICON

Precise leak detection for battery modules and packs
Detects smallest traces of electrolyte vapors
Identifies defects leading to battery degradation
Pinpoints leaking cells for efficient rework
Localizes microscopic leaks for manufacturing feedback

The BES4000 Electrolyte Sniffer Leak Detector is a precise and advanced leak detection system designed for battery modules and packs. It utilizes electrolyte sniffing technology to detect even the smallest traces of electrolyte vapors escaping from defective cells, ensuring high battery safety in electric vehicles. This system enhances the longevity of battery packs by identifying defects that could lead to rapid degradation, ultimately reducing warranty costs. The BES4000 supports various testing methods, including accumulation testing within closed battery packs, and is compatible with large-format packs and cell-to-pack architectures. It features a color touchscreen display for intuitive navigation, a calibration port for easy operation, and a sniffer probe with a dual-inlet design to minimize false alarms and enable precise leak pinpointing. The BES4000 is ideal for end-of-line leak testing and complements the ELT Vmax for a complete quality control solution, ensuring reliable and efficient battery production.
