Title:
MOISTURE SENSOR AND CORROSION TEST METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2019200141
Kind Code:
A
Abstract:
To provide a moisture sensor 1 for evaluating corrosive environment strength under a coating film.SOLUTION: The moisture sensor includes a sensor body formed with a first metal material 11 and a second metal material 12 differing in standard electrode potential that are alternately laminated, with an insulating member 13 therebetween. The sensor body includes an outcrop where the first metal material 11 and the second metal material 12 are alternately exposed, with the insulating member 13 therebetween, the outcrop constituting a sensor surface 6. Moisture is detected on the basis of a corrosion current that flows when the first metal material 11 and the second metal material 12 are electrically shorted due to moisture on the sensor surface 6.SELECTED DRAWING: Figure 2
