検知機構付防食装置。 An insulating member that fits into and seals an opening in the body wall of a metal hot water storage can whose inner wall surface is glass-lined, and an insulating member that penetrates the insulating member and is inserted into the can. It is equipped with a rod-shaped main electrode, a DC power circuit that is electrically connected to a terminal of the main electrode that protrudes outside the can body and the outer wall surface of the can body, and that passes a DC current between the main electrode and the can body, and is further insulated. An auxiliary electrode that penetrates the member and is provided near the inner wall surface of the can body and has a surface area smaller than that of the main electrode, a terminal of the auxiliary electrode that protrudes outside the can body, and a DC power supply circuit. A current detection circuit that is electrically connected to the positive side and detects the current value flowing between the auxiliary electrode and the can body, and a current detection circuit that detects the current value flowing between the auxiliary electrode and the can body. A corrosion protection device with a scale detection mechanism, comprising an output means for outputting a notification signal for removing attached scale.
