[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; in these occasions where the conductivity is used as an intermediate variable for other parameter detection, a certain parameter is required. A stable and accurate conductivity detection device; at present, during the passivation treatment of the aluminum profile surface, due to the harsh environment on site, the solution is extremely corrosive, and may accumulate scale, which requires regular maintenance. Only a few foreign manufacturers have installed instruments It is used in domestic production sites, and there are almost no conductivity detectors produced by domestic manufacturers; therefore, it is necessary to design a set of conductivity detection and control devices for the passivation process of aluminum profiles that are matched with seven-electrode sensors and can be networked. Anti-scaling; Most of the equipment imported from abroad is expensive and difficult to repair and maintain
