Our Electrochemical Workstations ZENNIUM X / ZENNIUM Pro / ZENNIUM  base on an universal and modular data acquisition system. Together with the THALES software package we offer all standard electrochemical methods at a mouse click.



CIMPS is an universal photo- and spectro-electrochemical workstation for a wide field of applications. You can easily extend the basic CIMPS system with various options for special fields of photo-electrochemical research.


Energy Storage & Conversion

Our power potentiostats, electronic loads and multi-channels acquisition systems provide a smart system for research and investigation on batteries, fuel cells and super caps.



Electrochemical noise has become popular as a new method of corrosion detection and prevention. ZAHNER has developed the CorrElNoise® technique, the first method to obtain both, potential noise and current noise from one electrochemical source.


THALES Software Package

The powerful THALES software package is part of the standard equipment of each  ZENNIUM system. It provides a multitude of measuring and analysis methods.

The THALES software provides unique features for acquisition and analysis. The most prominent examples are SCRIPT and SIM. SCRIPT offers you to combine all types of electrochemical measurements, mathematical analysis, algorithms, documentation and data export to a reproducible, fully automatic process. With the outstanding features of SIM, you are able to create equivalent circuits and fit the measurement data to these models. The ZHIT feature of SIM helps you to validate your impedance spectra.

For evaluation only it is also possible to run THALES Software Package on a THALESBox. The Thalesbox provides a single user licence of THALES. So you can process your recorded data on a simple PC or Laptop while your tests still run on your ZENNIUM system ...

System requirements:
• IBM compatible PC with Microsoft® Windows® 32-/64-Bit operating system
• Designated driver for Windows® 7, Windows® 8 and Windows® 10
• USB 2.0

Basic Functions & Methods

Electrochemical Impedance Spectroscopy (EIS)

EIS measures the impedance of your test element at different frequencies. This impedance spectrum characterizes the individual partial elements of your test system.

Applications: Determine different parameters like diffuision capacity, ohmic resistance, and so on.

(Multi Cell)I/E Scans & Cyclic Voltammetry (IE, CV)

I/E and CV measures voltage current curves in many different modes.

Applications: Tafel Scans, CVs, steady-state-, sampling - & dynamic current/voltage scans, fast cyclic voltammetry, potentiostatic/galvanostatic polarization, voltage/current vs. time, linear scans, multiple cell parallel dynamic I/E characteristics.

Single Frequency Impedance Measurement over Parameters (CE)

CE measures the impedance at a fixed frequency vs. other variable physical dimensions.

Applications: Fixed frequency impedance course vs. potential, current, time, temperature...

Universal Userdefined Measurements (PVI)

PVI allows voltage/current/time measurements in a userdefined way (steps, ramps, plateaus, loops, ...).

Applications: ...

Signal Acquisition (ACQ)

ACQ is an interface for a lot of additional measurement channels.

Application: Setup and integrate TEMP/U, DIO, DA4, Eurotherm, virtual instruments and so on...

Polarography Measurements (PGY)

Polarography offers the following methods: tast polarography, differential pulse polarography and differential pulse voltammetry (stripping voltammetry)

Applications: ...

Equivalent Circuit Simulation & Model Fit (SIM)

Process time dependent spectra and analyze the parameter course of model series.

Applications: Investigate spectra measured by EIS, smooth diagrams, select samples, edit equivalent circuit models, fit single/series measurements, analyse transfer function series and analyse measure series.

Import External ASCII Data (ALEX)

Import external ASCII data listings into thales environment for analysis.

Applications: This function offers you a unique interface for different kinds of data formats.

Automatize Measurements Script Server (SCRIPT)

Automatize combined measurement, analysis- and documentation tasks. Integrate situation dependent processing, branches, loops and so on.

Applications: SCRIPT enables each user to create his own procedure in an easy-to-learn BASIC-like language which uses a lot of powerful macro-commands. If needed, a complete set of andiBASIC commands is available. This makes measurements comfortable and easy to handle - even for untrained staff.

Call/Integrate SCRIPT Runtime Modules (EXE)

With EXE you can start SCRIPT runtime modules in an easy way.
Application: Integration of ready linked scripts in the thales main screen and special applications like CIMPS, COLT, RV, REMOTE, ...

Assemble, Edit & Export Graphics (CAD)

CAD is the thales graphic editor for ICD-formated graphic files.

Application: Edit graphics/diagrams/reports, customize screenshots, export graphics to enhanced meta files (EMF) or clipboard.

DC Cycling Script for Battery Applications with AC-EIS Spectroscopy During Ramps (BAT)

Battery Cycling is a script application for automated DC cycling with AC-EIS spectroscopy during ramps.

Application: Battery applications

TCP/IP VI Remote Control Script

Normally, the ZENNIUM systems are controlled by the THALES software package, which is optimized for measuring and analyzing electrochemical data. In addition, the electrochemical workstations are prepared to be controlled by an external software using the TCP/IP protocol. This is not limited to the local workstation PC, but is also possible over network.

Application: Controlling the basic functions of your ZENNIUM system by a LabVIEW® VI over TCP/IP
