The PAT-Cell-TwinRef is a special version of the PAT-Cell supporting the use of a second reference electrode. This way you can simultaneously measure with two reference electrodes, for instance with LFP and LTO. Since both ring electrodes are arranged face-to-face, their SOC can be easily adjusted. Ability for conducting long-term half cell measurements with two reference electrodes. Compatible with any potentiostat or battery tester.
