ABSTRACT:
A self-contained, disposable corrosion monitor for a fluid containing system comprising a plug insertable into a fluid containing system, the plug indicating a preselected amount of loss of metal on an inner wall of the system due to corrosive action of the fluid on the inner solid monitoring wall of system. The plug includes a wall of the predetermined metal having a thickness equal to the preselected amount of loss and one surface exposed to the fluid when the plug is inserted into the fluid containing system at the same level as the inner wall of the system, an enclosed cavity associated with the other surface of the monitoring wall and a substance disposed within the enclosed cavity reacting with the fluid penetrating the monitoring wall to indicate when fluid has penetrated the monitoring wall and, hence, that the preselected amount of loss of the metal on the inner wall of the fluid containing system has occurred.
