Product Description
The PAT-Tester-8 delivers eight high-precision measurement channels in a compact design. Stackable and compatible with 19-inch racks, it adapts to your needs — from single-cell tests to high-throughput setups. Its state-of-the-art electronics, shared with the proven PAT-Tester-i-16 and PAT-Tester-x-8, offer fully independent potentiostat /galvanostat and EIS functions, ideal for precise measurements on small-format battery cells. Specially shielded cell cables minimise interference and ensure reliable results.
The PAT-Tester-8 comes with EL-Software, providing comprehensive tools to design, manage, and monitor your experiments with ease. It supports all EL-CELL battery test cells and can also connect to other cell formats.
