An IBM-XT personal computer was connected to an Isaac 91 I Analog-to-Digital and Digital-to-Analog multiple function interface, to perform electrochemical impedance measurements for corrosion testing. The method of measurement, software and hardware configuration are described. The system performs complex impedance measurement automatically covering the frequency range 0.001 to 1 Hz without operator intervention. Quick, semiautomatic operation covers the 2 to 200 Hz range. Data processing, storage and graphic presentation are automatic. The presentation exemplifies approaches to utilize the potential of personal computers in corrosion measurement applications.
