Multi-channel EIS-Meter
The multi-channel impedance spectrometer “Multi-channel-EIS-Meter” is a high-precision impedance analyzer that has been specially developed for laboratory applications, test benches and industrial use. Thanks to the optimization for very low impedances in the micro-ohm range and a total voltage of up to 1000 V, the device measures even low impedances extremely precisely.
All channels are recorded synchronously. This enables an exact comparison of the data and offers a clear advantage over asynchronous multiplexers. The high common mode rejection ensures accurate measurements, even in demanding environments.
The system is available in various configurations - for example with 8, 12, 24, 36, 48, 60 or even more channels. It offers numerous interfaces for seamless integration into industrial applications. The multi-channel impedance spectra are measured directly under real operating conditions, providing users with reliable data for in-depth analysis.
Online analysis functions enable continuous monitoring and immediate evaluation of the measurement data in real time. Typical applications are the measurement of impedance spectra of single cells or cell groups in fuel cell stacks (PEM, SOFC), in battery packs and in electrolysis stacks (AEL, AEM, SOEC).
