ABSTRACT:
A method of measuring the rate of corrosion of a metallic structure that is subjected to a corrosive ambience. It subjects a thin metallic enclosure to the same ambience as the metallic structure is subjected to. The thin enclosure is subjected to the ambience on one side, while it maintains a different condition on the other side of the enclosure. Then, it detects a change when the different condition is no longer maintained due to the thin enclosure having corroded through.
A probe for detecting the corrosion rate of metallic piping or the like. It includes a thin metal enclosure mounted with one side subjected to the corrosive ambience acting upon the piping. There is means for subjecting the other side of the thin enclosure to a condition that is different from that of the corrosive ambience. And, there is a means for detecting a change of the different condition when the thin metal enclosure corrodes through.
