Abstract :
According to the characteristic of the two-electrode conductivity cell, a conductivity measurement system of high precision was designed based on the signal processing technology. The paper described the principal of square wave excitation for conductivity measurement, the system hardware design and software working process. Experiment results show that the system has the feature of high precision, wide scale range and fast measurement, and it could be applied in laboratory instruments and industry devices.
