ECstat-302C Potentio / Galvanostat Analyzer (Original: EC Frontier, Japan)

(2026 Upgraded version) The ECstat-302C is a compact single-channel potentiostat/galvanostat for electrochemical research and battery testing. It supports multi-potential monitoring and a broad range of routine electrochemical measurements. Optional ECstat Advance software enables automated sequences and coordinated multi-device workflows, while ECboost-4002C extends the system for higher-current applications. Key Features Multi-Potential Monitoring: Simultaneously records WE–RE, WE–CE, and CE–RE voltages, providing enhanced visibility into electrode behaviour and cell-voltage distribution. Automated Experimental Workflows: Supports user-defined sequences, repeated cycles, event-based control, and coordinated operation of multiple compatible devices through ECstat Advance. Versatile Electrochemical Testing: Supports routine electrochemical measurements, electrode-resolved potential monitoring, and dedicated charge-discharge workflows for electrochemical cells and battery systems. Expandable Current Capability: Provides standard operation up to ±30 mA and can be expanded to ±300 mA using the optional ECboost-4002C current booster.
