The IM7x is Zahner's flagship modular potentiostat / galvanostat including a frequency response analyzer (FRA). It offers 32-bit DC and 24-bit AC resolution across 12 current ranges for outstandingly precise measurements.

With an EIS frequency range of 10 µHz to 12 MHz, a compliance voltage of ±32 V and a maximum current of ±4 A, the IM7x is designed for the most demanding electrochemical tasks across fundamental electrochemistry, batteries, fuel and electrolysis cells, and corrosion and coatings.

Addon Cards

Plug-and-play cards introduce additional input/control signals to the IM7x potentiostat:

• PAD42 — 24-bit synchronous measurements on each cell in stacked systems (batteries, fuel & electrolysis cell stacks) and simultaneous half-cell characterization
• MIO — Additional analog & digital I/O channels (16-bit resolution, ±10 V); process automatization via Custom Experiment Builder or remote integration
• TEMP-U2 — Two temperature recording channels and two configurable input-voltage channels for external devices (pH meter, pressure chamber, etc.)

Extensions For Power Applications

• Medium power (PP series) — Power potentiostats up to 200 W, current up to ±40 A, voltage up to ±20 V; remote via C++ and Python
• High power (EL series) — Electronic load system up to 68 kW, current up to ±680 A, voltage up to ±100 V; remote via C++ and Python

Remote Integration

Remote control via C++, Python and WebSocket using the zahner_link library (Ethernet/WebSocket). Multiple potentiostats can be integrated into a test bench to create a multichannel system.
