Implementation of an electrochemical impedance meter I

Abstract

Current circumstances motivate University to implement import substitution policies in order to minimize cost of equipment, maintenance and repair. In agreement, schools of Ingenierías Eléctrica, Electrónica y Telecomunicaciones y de Ingeniería Metalúrgica y Ciencia de Materiales, are developing a project for the construction of equipment, oriented to academic and research activities, that can be checked and repaired in situ. This paper presents the design and construction of an electrochemical impedance meter to be implemented in the laboratory of corrosion of the EIMCM. 

An Electrochemical Impedance Meter is defined as a computer that allows electrochemical test with alternate current, in order to determinate corrosion on a material, providing a controlled voltage difference at different values of frequency and acquiring the value of current flowing through an electrochemical cell.
