ABSTRACT:
A method for measuring the surface area of an electrically surface-conductive body comprises applying an a.c. voltage between the body and a corrosion-resistant opposite electrode, both being immersed in an electrically conductive solution having no corrosive influence upon the surface of the body. An electric capacity value for the body is obtained. The measured value is inserted in the function of a surface area and a similar measurement or value obtained using another body having a known surface area in a similar manner. If the body to be treated does not exhibit surface conductivity, the body may be coated on the surface with a conductive material.
