[0002] In the chemical reaction process, the conductivity is an important parameter of the solution, its size directly reflects the conductivity of the solution, and is closely related to the concentration of the electrolyte; the concentration of organic matter can also be converted into conductive substances through appropriate reactors, and then Measure the change in conductivity before and after the reaction, and then calculate its concentration; in addition, there is a type of semi-electrolyte whose concentration is also closely related to conductivity under high-frequency excitation; these are carried out with conductivity as an intermediate variable. For other parameter detection occasions, a stable and accurate conductivity detection device is required. At present, the conductivity detectors produced by domestic manufacturers generally use a resistance box to manually verify the conductivity meter, which is cumbersome to use and has a low degree of automation; Or the influence of wires on conductivity detection is not considered, which seriously affects the self-calibration accuracy and detection accuracy, especially in the case of high-frequency excitation; most of the equipment imported from abroad is expensive and difficult to maintain
