Abstract

The invention provides an automatic potentiometric titrator which comprises a controller, a titrator body and a titration area, wherein an electric connecting wire is arranged on the outer surface of the titrator body; the controller is mounted on the electric connecting wire; a fixed rod is arranged at the rear end of the titrator body; a fixed head is mounted above the fixed rod; a solenoid valve is connected with the right end of the fixed head; a burette is mounted on the solenoid valve; an electrode fixing frame is connected with the right end of the solenoid valve; an indicator electrode and a reference electrode are welded under the electrode fixing frame; the burette, the indicator electrode and the reference electrode are arranged above the titration area; the titration area is arranged on the upper surface of the titrator body. The automatic potentiometric titrator has the beneficial effects that the titrator body can automatically start titration after a user puts a to-be-detected solution into a specific bottle and then places the bottle above the titration area, and the titrator body can automatically stop working after the completion of the titration, so that manpower and electric power resources are saved; the design is smart, the market competitiveness is promoted, and the purposes of simple structure and reasonable design are achieved.

Description

technical field [0001] The invention is an automatic potentiometric titrator, which belongs to the field of chemical equipment. Background technique [0002] The determination of the electrode potential is realized by measuring the electromotive force of the primary battery composed of the electrode to be tested and the reference electrode. Therefore, the potentiometric measuring instrument uses a reference electrode, an indicating electrode, and a measuring instrument to form a loop to measure the electrode potential. There are two types of potentiometric measuring instruments: direct potentiometric measuring instruments and potentiometric titration measuring instruments. [0003] Direct potentiometric instruments include a pH meter that uses a pH glass electrode as the indicator electrode to determine the acidity and an ion meter that uses an ion-selective electrode as the indicator electrode to measure the concentration of various ions. Because many electrodes have high...
