The EIS-meter represents a pioneering innovation in the field of high-precision impedance spectrometry, specially developed for test objects with extremely low electrical impedances in the micro-ohm to milliohm range, such as those found in batteries, fuel cells or electrolysers.

The EIS-meter owes its exceptional accuracy to a pioneering modulation current source that is capable of generating modulation currents of up to ±50 A. This achieves outstanding measurement results even at high DC currents, making it an indispensable tool for precise analysis and research.

 

Thanks to its versatility and flexibility, the EIS-meter is suitable for a wide range of applications. The smallest version is perfect for detailed analysis of individual cells and can measure voltages of up to 10 V and DC currents from 100 A to over 2,000 A. This compact version is ideal for both laboratory and desktop applications.

For test objects with higher voltages of up to 1,000 V, the EIS-meter is supplied in a robust 19" rack. This version is also designed for high DC currents over 2,000 A and can be seamlessly integrated into test benches. Thanks to its automation interfaces, it can be easily integrated into control and automation systems.

The EIS meter not only enables the measurement of entire stacks, but also the detailed analysis of individual cells or cell groups within the stack. This makes it an indispensable instrument for research, development and quality control in the battery and energy industry.
