Customizable Potentiostats: IM7 / IM7x
Zahner's potentiostats (IM7x or IM7) are modular high-end potentiostats and can be customized with diverse extension options (i.e., add-on cards and/or power boosters). The potentiostats can be fundamental electrochemical research and can be customized for charactization of fuel-, electrolysis- and battery cell/stacks.

Medium power extensions
The IM7 series potentiostats can be extended with power potentiostats (PP-series) for use in medium power applications (up to 200 W). These setups can perform all measurements (DC+AC type) which are possible with the IM7-series potentiostats.
High power extensions
The IM7 series potentiostats can be extended with the electronic load and can be used for high power applications (up to 1 kW).
The Zahner's electronic loads are one-quadrant potentiostats and can only be used as a sink. The electronic loads are designed for measuring clean impedance spectra even at high DC currents.
For electrolysers or state of charge measurements, an external power supply is required. With an external power supply, high power applications (up to 68 kW) are possible.
Multi cells measurements
An IM7 potentiostat can be extended with a PMUX or BC-MUX multiplexer and electrochemical measurements on multiple cells can be carried out sequentially. A script for automizing the measurements at different cells is also possible.
A BC-MUX is connected parallel to a battery cycler and can disconnect the battery cycler from the battery and carry out the EIS on the battery. After the measurement, the battery is connected back to the battery cycler.
Probes
Special probes are used for dedicated experiments like high impedance, very low impedances or very low capacitance measurements. These probes mitigate the artefacts common to the above-listed measurements. Probes are also available which extend the operation range of the ZENNIUM series potentiostat like CVB120, FRA-Probe and Noise Probe.
Addon Cards
The addon cards introduce additional analog and digital input & output signals to the ZENNIUM potentiostats. For example, a PAD4 card provides 4 additional voltage sense signals which can be used to record voltage during the measurement or a TEMP/U card which is used to measure temperature or voltage during the measurement.
The addon card EPC42 is used to connect ZENNIUM potentiostat with power potentiostats and electronic loads. An EPC42 card can connect up to 4 power potentiostats or electronic loads which can be used sequentially.
