Determination of the polarization resistance from multiple sensors under computer control provides rapid, reproducible and accurate means for determining corrosion rates ranging over many orders of magnitude for large test matrices. Computerized techniques can simultaneously evaluate the response of many sensors to variations in the composition of a corrosive environment. Examples are presented of computerized corrosion monitoring of atmospheric corrosion rate monitors subjected to pollutant transients, and of materials in simulated flue gas desulfurization media containing trace elements.
