Japanese Patent JP7104326
Kind Code:
B2
Abstract:
To provide a corrosivity evaluation device that quantitatively evaluates corrosivity that represents an extent to which metal is corroded by an environment. A corrosivity evaluation device evaluates corrosivity that represents an extent to which metal is corroded by an environment, the device including: an electrode unit containing at least one type of the metal by being placed in the environment; a measurement unit adapted to measure a corrosion rate of the metal or a value related to the corrosion rate of the metal during one cycle of change in water content of the environment, the measurements being taken from the one cycle of change; and a calculation unit adapted to calculate a corrosion amount of the metal or a value related to the corrosion amount of the metal from the value measured by the measurement unit.
