Xinrui ZD-2 Titrator is an analytical instrument designed according to the principle of potentiometric titration and used for volume analysis. The appropriate indicator electrode and reference electrode are selected to form a working cell with the test solution, and with the addition of titrant, the concentration of the measured ions is constantly changing due to a chemical reaction, and thus the potential of the indicator electrode changes. Near the titration endpoint, a sudden change in the concentration of the measured ions causes a sudden jump in the electrode potential. Thus, the titration endpoint can be determined based on the sudden jump in the electrode potential. Used for the chemical analysis of various components in colleges and universities, scientific research institutions, petrochemical industry, drug testing, metallurgy and other industries.

The instrument adopts the new microprocessor technology, which can simultaneously display the year, month, day, time, working status prompt, measurement results and other information.
The instrument has a good man-machine dialogue operation interface, Chinese and English switching display, easy to use.
The instrument has a variety of titration modes including manual titration, automatic titration of preset endpoints, potentiostat (PH) titration and pH measurement, potentiometric measurement, and other functions.
The instrument uses a microprocessor to control the amount of liquid dropped by the solenoid valve, and the detachable titration device is convenient for users to replace. It has the advantages of easy use and simple maintenance.
The instrument is equipped with a magnetic stirring system, using PWM modulation technology, software speed regulation, stable and reliable.
