Abstract
A method of measuring an electrochemical corrosion potential (ECP) of a material specimen using a detecting device including an ECP detecting array is provided. The method includes locating an offset spacer in close contact to a face of the ECP detecting array, locating the material specimen within the detecting device with a measurement face in close contact to the offset spacer, establishing a flow through the detecting device, and measuring an electrical potential between the detecting device ground and an electrode wire.
