ALDAS High-Speed EIS System for Real-Time Impedance Analysis
Product information ALDAS High-Speed EIS System for Real-Time Impedance Analysis
The ALDAS-α is a high-performance electrochemical impedance spectroscopy (EIS) system designed for analyzing fuel cells and water electrolysis. While conventional current-voltage (I-V) measurements are widely used to evaluate overall cell performance, they are limited in identifying the underlying causes of performance changes or degradation.
Using EIS, the ALDAS-α enables a deeper analysis by quantitatively evaluating and separating complex electrochemical phenomena within the cell. This provides a more detailed understanding of internal processes.
Thanks to its high-precision current sensing technology, the system delivers stable and accurate impedance data from very low frequencies, ensuring reliable and easy-to-interpret results.
A key benefit of the ALDAS-α system is its fast measurement speed, completing scans in less than 8 minutes [OW2.1]- significantly reducing test time compared to conventional systems. With support for simultaneous multi-channel measurements up to 8 cells and up to 20 A DC output, the ALDAS-α system reduces development time considerably.
The ALDAS-α is the ideal choice for high-speed, multi-channel EIS measurements in R&D environments where precision and efficiency matter most. It is one of HIOKI’s EIS measurement solutions, alongside the compact ALDAS-Mini and the high-power ALDAS-E.
