Method of measuring corrosion rate using ACM sensor and environmental monitoring device

摘要

To provide a corrosion rate of a metal material in an atmospheric environment without rain, ACM sensor can not calculate the rate of corrosion of a metal material in an atmospheric environment where rain is applied. Provided are a corrosion rate measuring method and an environmental monitoring device using an ACM sensor capable of measuring corrosion even in a rainy atmosphere and extending the life of the ACM sensor.SOLUTION: The corrosion rate can be measured by switching between the current measurement method and the potential measurement method by using the ACM sensor 1, and in the atmospheric environment where the ACM sensor 1 is not subject to rain, it is measured using the current measurement method, In the atmospheric environment where rain is applied to the ACM sensor 1, it is measured using a potential measurement method.(FIG.
