A method and apparatus for monitoring and reporting corrosion in terms recognized as conforming to an industry standard includes coating a substrate with a corrodible metallic substance of predetermined thickness, passing a current through the metallic substance, and generating a signal when electrical continuity is broken due to corrosion of the metallic substance. In one embodiment the apparatus includes a printed circuit board onto which the coated substrate is mounted, a power source for applying an electrical current across the coated substrate, and a display (such as a light or LCD panel) for providing an indication/alert that electrical continuity has been broken due to corrosion of the metallic substance. A corrosion sensor according to the present invention finds application in such environments as industrial process measurement and control rooms, motor control centers, electrical rooms, semiconductor clean rooms, electronic fabrication sites, commercial data centers, museums, libraries, and archival storage rooms.
