Another use is the testing of batteries. The potentiostat is a circuit design that provides a working potential to the electrodes and adjusts the current signal among the three electrodes to an appropriate level. For many op-amps/potentiostats this is typically 10 V or 15 V. As a stand-alone device the op-amp thus has little practical use as an amplifier. EIS, featured, FRA, Galvanostat, Multipotentiostat, Potentiostat; Model 2560 can power up to eight units (2559 or 2700) being all connected to the same computer.
