IM7c
The IM7c is a compact potentiostat / galvanostat including a frequency response analyser. It offers 32-bit DC resolution and 24-bit AC resolution across 12 different current ranges, which ensure exceptionally accurate and precise measurements.
The IM7c can either be operated by Zahner Lab or by the zahner_link API. The zahner_link libraries communicate with the IM7c via WebSocket connections, exchanging JSON objects. Built with a C++ core, the zahner-link also offers Python bindings for simplified programming.
The main specifications for the IM7c are
