Device and method for automatically measuring ions in water by adopting anti-pollution pH electrode

The invention relates to a device and method for automatically measuring ions in water by adopting an anti-pollution pH electrode. The device comprises a measuring cell, a stirrer arranged in the measuring cell and a standard hydrochloric acid solution supply mechanism communicated with the measuring cell. A pH electrode and an ORP electrode are arranged in the measuring cell, and the pH electrodeand the ORP electrode are connected with a control system through a signal plate; the standard hydrochloric acid solution supply mechanism comprises a standard hydrochloric acid solution pool and a standard hydrochloric acid solution supply pipe connected with the standard hydrochloric acid solution pool, the end of the standard hydrochloric acid solution supply pipe is connected with the measuring pool, and a metering pump is installed on the standard hydrochloric acid solution supply pipe. According to the device, the titration end point is recognized through the pH electrode and the oxidation-reduction electrode,
