The EIS meter - SIVONIC Products

SIVONIC's EIS-Meters are electrochemical impedance spectrometers and can cover a very wide range of impedances, currents and voltages.

Devices are available for very small electrical impedances in the microohm [µΩ] and milliohm [mΩ] as required for the investigation of modern battery cells and fuel cells.

Furthermore, there are devices for very high test object voltages up to 1,000 V. These are used for the investigation of DUTs with high voltages such as fuel cell stacks, electrolyser stacks and battery packs.

The multichannel impedance spectrometer “Multichannel-EIS-Meter” is a high-precision impedance analyzer for laboratories, test benches and industrial applications.

It measures the smallest impedances in the micro-ohm range at voltages up to 1000 V and enables time-synchronous acquisition of all channels. Thanks to high common mode rejection, it delivers accurate results, even under demanding conditions.

The system is available with up to 60 or more channels and can be seamlessly integrated into industrial processes. Online analysis functions enable real-time monitoring of the measurement data. Typical applications include impedance measurement in fuel cell stacks, battery packs and electrolysis stacks.

SIVONIC's calibration equipment, which is configured according to customer requirements, enables optimally matched measurement results through individual calibration of the installation setup.

As a supplement to the EIS-Meter, highest accuracies and reproducible measurement results can thus be achieved because the entire measurement system is adjusted to the individual conditions of the measurement environment. The tuning can itself be aligned to the DUT geometries.
