ABSTRACT:
A method for testing anticorrosion performance of an aqueous protective fluid by immersing a testing electrode comprising a plurality of individual electrodes insulated from and spaced with respect to one another into an aqueous protective fluid; immersing a reference electrode into the aqueous protective fluid at a predetermined distance from the testing electrode; connecting an Ohmmeter sequentially between each of the individual electrodes and the reference electrode to measure a plurality of electrical resistances between each of the individual electrodes and the reference electrode whereby obtaining a distribution of resistances. The distribution of resistances defines the anticorrosion performance of the aqueous protective fluid.
