The work of this paper is to develop an electrochemical measurement system controlled by personal computer via AD/DA interface board based on LabVIEW platform. In the electrochemical measurement system

the computer generates the external control signal

acquires the polarization potential and the polarization current of the work electrode

displays their voltammetry curve and saves the data in the text file in the end. At present two conventional measurement methods of linear sweep voltammetry and cyclic voltammetry have been realized in this system. The polarization curves of some ordinary materials had been measured by means of the constructed electrochemical measurement system. The measurement results had pointed out that this system works well and acquired data is exact.
