A complete study of a copper electrodissolution experiment is achieved, The asymptotic motion settles down on a strange chaotic attractor which may be embedded in a 3D reconstructed space. In a 2D Poincare section the attractor is found to be topologically equivalent to a 1D map, and its orbit spectrum is governed by the unimodal order. A set of equations which suitably model the experiment is extracted by a global vector field reconstruction method. The attractor obtained by integrating the reconstructed system is topologically equivalent to the original attractor. It is shown that the reconstructed model represents the dynamics without taking into account the effect of the dynamical noise on the experiment.
