Abstract: An electrochemical testing system, including: a testing board including: a plurality of testing wells, each well including a first well portion for holding a workpiece to be tested and bringing a first surface of the workpiece into contact with a separate working electrode lead for each testing well, a second well portion for holding a testing media and bringing a second surface of the workpiece into contact with the testing media, and a sealing mechanism for preventing contact of the testing media and the first surface of the workpiece; a media delivery system for selectively delivering the testing media into the second well portion; at least one sensing head for securing one or more electrochemical sensing elements at least one of which is adapted to form part of an electro chemical circuit with the testing media, workpiece and working electrode lead for each testing well, each testing well being electrically and physically isolated from other testing wells; testing apparatus for measuring electrochemical a
