FRA-X

The FRA-X acts as an interface between a ZENNIUM potentiostat and an external potentiostat and allows EIS measurements outside of the power specifications of Zahner's potentiostats. The input channels of FRA-X are galvanically isolated from the external potentiostat and the test object. In addition, high resolution and in-phase recording enables high-quality EIS measurements even at very high DC currents.

The FRA-X offers current ranges of ±500 A, ±1000 A, ±2000 A, or user-defined.

Potentiostats for Electrochemistry & Photoelectrochemistry

Since 1976, the German company Zahner-Elektrik is developing and manufacturing innovative high-precision instruments such as potentiostats and galvanostats for all kinds of electrochemical and photoelectrochemical applications. Our multi-disciplinary team of developers is always in contact with users and at the same time at the front line of technology development.

Potentiostat customized to suit your needs.

Zahner potentiostats can be equipped with multiple plug and play addon cards, which introduce additional analog and digital in- & output signals. This modular function makes Zahner's potentiostats very flexible and allows the possibility to customize the potentiostat to suit the needs of its users.

The available extensions allow DC and AC measurements across a broad current range.

Remote control of ZENNIUM potentiostat

The ZENNIUM potentiostats can be incorporated in a C++, Python or LabView environment and can be operated remotely.

The C++ and Python libraries to control Zahner devices are available in our GitHub repository. In addition, multiple sample projects are also provided which users can adapt for their own experiments.

Zweipol-Hilbert transformation

Zweipol-Hilbert transformation (Z-HIT) allows the detection of non-stationarity and mutual inductivity in the measured EIS spectrum. The limitation of Kramers-Kronig does not apply to Z-HIT which ensure a better evaluation of the measured EIS spectrum than Kramers-Kronig transformation. .

ZHIT approximation

Non-linear frequency response analysis (NFRA)

For NFRA, a large excitation amplitude for impedance spectroscopy excites both the linear and the non-linear processes. Online Fourier transformation and signal processing allow to record these linear and non-linear response signals. These non-linear responses allow further insight in to the system under investigation than EIS. 

Intelligent multi-sine

In intelligent multi-sine measurements, multiple excitation signals are generated simultaneously. This shortens the EIS measurement time without compromising the quality of the measurement.

Intelligent multisine EIS

C in CIMPS

Zahner's CIMPS system is developed for characterizing the PEC and PV systems. The CIMPS system ensures a constant and controlled light illumination during the measurement. Ability to precisely control the light intensity during the measurements makes the CIMPS one of its kind and much better setup than traditional setups for PEC or PV characterizations.

Scripting and remote control

Zahner Script: 
Simple scripts can be written to automize the measurements one after another. The user can define different conditions for the start of measurement or realize complex measurement procedures. An manual for scripting is provided in this manual.
 
Python integration:
The Zahner's potentiostats can be incorporated in a C++ or Python lab environment and can be used as stand-alone or in multi-channel configurations. For C++ and Python, GitHub repositories with the libraries and various examples are available.
