　　ABSTRACT

 

　　The present invention provides a method for simultaneously and continuously monitors the overall working of the metal electrode and the two corrosive localization method and apparatus, wherein the low-frequency, low-amplitude periodic excitation is used for the potential interference with the free corrosion potential in the vicinity electrodes. By means of constant potential relative to the reference electrode to control the electric potential, and the auxiliary electrode is used to facilitate current flow. The current response of the working electrode as a whole and localized corrosion activity is continuously monitored and analyzed. Means are provided for validation on the applied potential excitation current response integrity. As a whole as well as localized corrosion activity both simultaneous and continuous output is also provided.
