Knowledge of the precise surface area of an electrically conducting body is needed in electroplating processes for determining important parameters such as current density. The main principals of a surface area measurement method are presented in this paper. A theoretical basis of the diffusion-limited current method (DIM) for measurement of the surface area of an electrically conducting body is explained. An intelligent measurement system for measuring surface area based on DIM is described, including realization of the hardware and software. Results of experiments concerning accuracy, limitations and implementation area of the measurement system are given.
