Electrochemical Instruments are the class of instruments that find application in electrochemistry, which is a branch of chemistry that studies chemical reactions involving an electron conductor and an ionic conductor. In such reactions, transfer of electron takes place between the electrode and the electrolyte.

Potentiostat, galvanostat and zero resistance ammeters are some of the most common types of instruments classified as electrochemical instrument. For example, a potentiostat is used to control the voltage difference between a working electrode and a reference electrode both of which are contained in an electrochemical cell. Likewise, galvanostat is an instrument that controls the current through an electrochemical cell at a preset value. Thus, electrochemical instruments are used for various purposes in electrochemistry.
