A PC based system for conductivity measurement has been designed and developed for chemical rate determination. Aprecise operational amplifier (LM308) is used as amplifier formeasuring conductivity of electrolytic system. The temperature measurement is also provided in the system since the conductivity of the solution varies with temperature. The paper deals with the hardware and software details.
