Objective To design a circuit for detecting dissolved oxygen. Methods Multi-channel polarograph covering electrodes were used to detect the water solution. The current signal from electrodes was converted into a voltage signal by the signal mediation circuit. After temperature compensation based on C8051F020 control system, weighted average sampling values were obtained as the measured values. Results The circuit realized real time detecting of dissolved oxygen, and possessed the functions of parameter display, adjustment and analysis. Conclusion This circuit for dissolved oxygen detecting is high precision and stable. It has a good application prospect in research and development of water treatment equipment and environmental water quality monitoring.
