Abstract
Coupled multielectrode array sensors (CMAS) have been used for quantitatively monitoring corrosion, particularly localized corrosion in laboratories and industrial fields. The internal anodic current on the most anodic electrode in a CMAS probe may affect the measurement of the corrosion rate by the CMAS probe in cases where uniform corrosion, as opposed to non-uniform corrosion or localized corrosion, is dominant. This paper presents a method that can be easily implemented in a CMAS instrument to determine the effect of the internal current on the corrosion rate measured by the CMAS probe.
