EmStat4WE

With this polypotentiostat one electrochemical cell can be equipped with 1, 2, 3 or 4 working electrodes and all of these will be measured parallel. The EmStat3 4WE consists of a standard EmStat3 potentiostat and additionally three polypotentiostat (bipotentiostat-like) modules.
All techniques supported by EmStat3 are available for the EmStat3 4WE.
