METHOD FOR MEASURING CORROSION SPEED USING ACM SENSOR AND ENVIRONMENT MONITORING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring a corrosion speed using an ACM sensor and an environment monitoring device, which allow for corrosion measurement even in a rainy atmospheric environment and allow for extending the life of the ACM, in order to solving a conventional problem that a corrosion speed of a metallic material in a rainy atmospheric environment has not been fully addressed though the corrosion speed of the metallic material in a non-rainy atmospheric environment can be obtained by the ACM sensor.;SOLUTION: A corrosion speed can be measured using an ACM sensor 1 by switching between a current measurement method and a potential measurement method. The current measurement method is used for measurement in an atmospheric environment in which rain does not fall on the ACM sensor 1, and the potential measurement method is used for measurement in an atmospheric environment in which rain falls on the ACM sensor 1.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
