Problems solved by technology

[0002] Chloride ion detection is widely used in construction, medicine, environmental protection, electric power, petrochemical, heating and other industries. At present, chloride ion detection technology mainly adopts silver nitrate manual titration method, or a semi-automatic detector developed based on the electrode method as the end point judgment; Due to the characteristics of human participation, the artificial titration method has poor consistency in the detection process and large errors in the detection results. However, the semi-automatic detector developed based on the electrode method as the end point judgment is subject to the detection environment and impurity ions due to the slow chemical potential reaction. The interference will cause poor consistency of each measurement, and there will be errors
