Novel potentiometric titrator

The utility model relates to the technical field of potentiometric titrators, in particular to a novel potentiometric titrator, which increases the operation convenience and prevents collision caused by hand operation. Comprising a potentiometric titrator, a positioning pipe, a mounting beam, a connecting column, a mounting frame, an electric stirring rod, a composite electrode, a bolt, a liquid inlet pipe and a driving mechanism, the positioning pipe is mounted on the potentiometric titrator, the mounting beam is slidably mounted in a shaft cavity of the positioning pipe, the connecting column penetrates through a through groove of the positioning pipe to be mounted on the mounting beam, and a through hole of the mounting frame is slidably connected with the mounting beam in a matched manner; a plurality of mounting holes are formed in the mounting frame, the electric stirring rod, the composite electrode and the liquid inlet pipe are mounted in the mounting holes of the mounting frame, the bolt is in thread
