This paper describes an electrochemical research system based on the Lab VIEW computer software package. An overview of well known electrochemical methods, such as potential measurements, chronopotentiometry, chronoamperometry, cyclic voltammetry and EIS is given. Electrochemical impedance spectroscopy has been adapted for systems containing large capacitances. For signal generation and recording of the response of the investigated electrochemical cell, a measurement and control system was developed, based on a PC P4 computer. The rest of the hardware consists of a commercially available AD-DA converter and an external interface for analog signal processing. The interface is a result of the authors own research. The software platform for the desired measurement methods is Lab VIEW package, which is regarded as a high standard in the area of modern virtual instruments. The developed system was adjusted, tested and compared with other commercially available systems. One such system is in constant use at the Technical Faculty in Bor
