Potentiostats

The AMETEK SI product line includes Single Channel, MultiChannel and BiPotentiostats through both the Princeton Applied Research and Solartron Analytical brands.
A potentiostat is a device that measures the current produced by a chemical reaction at a given voltage. It maintains this voltage by sending power to an electrode called the counter electrode and measuring the resulting current between another electrode called the working electrode and a third electrode called the reference electrode. The potentiostat uses this information to calculate the cell potential between these two electrodes.
Researchers use our potentiostats to meet the most demanding scientific challenges. This includes testing new chemistries for Li-ion batteries, improving resistance to corrosion, determining concentrations of target analytes. A galvanostat is a type of potentiostat that controls the current flow between the working and counter electrodes while measuring the cell potential between the working and reference electrode.
