Corrosion monitoring using an electrical resistance (ER) technique is considered the most suitable method for evaluating variation in corrosion rates of steel due to varying atmospheric conditions. In this study, exposure tests of steels in Okinawa and Kawasaki confirmed that changes in corrosion rate throughout the year can be evaluated in detail by the ER technique, as well as the relationship between the corrosion rate and environmental factors (temperature, relative humidity, amount of airborne sea salt, etc.). The accuracy of the technique was confirmed by comparing corrosion losses evaluated by the ER technique to those of test specimens. Based on the results, the accuracy of the corrosion rate evaluated by the ER sensor was higher than that by a conventional ACM (atmospheric corrosion monitoring) sensor. The cause of the lower accuracy of the ACM sensor is thought to be the very low sensitivity of the ACM output to temperature, notwithstanding the high sensitivity to the actual corrosion rate.
