When the ph electrode detects that the ph in the solution is inconsistent with the preset ph value, the control system will automatically trigger the peristaltic pump. By adding acid or alkali until the ph in the solution is consistent with the preset ph, the peristaltic pump will stop working and keep the pH in the solution at a certain value.
