In particular, the Research Potentiostat is a high performance instrument and recommended as a “must have” instrument for any laboratories that use Potentiostats. It is also ideal for use in a teaching establishment, to give students a feel for corrosion. It can be configured as a two or three electrode Potentiostat, a Zero Resistance Ammeter and a Galvanostat. A graduated dial is used to set the potential of ±1V or ±4V and buffered potential and current outputs allow for connection to chart recorders. Also features external potential input (Ext In).
