The manufacturer of Automatic Potential Titrator takes you to understand the principle of the potential method

Automatic Potential Titrator is a common analytical instrument designed for capacity analysis based on the principle of potentiometric method.

       The manufacturer of Automatic Potential Titrator tells you that the principle of the potentiometric method is: select the appropriate indicator electrode and reference electrode to form a working battery with the measured solution, and with the addition of the titrant, the concentration of the measured ion is constantly changing due to chemical reactions , so the potential of the indicator electrode changes accordingly. Near the titration end point, the measured ion concentration changes suddenly, causing a jump in the electrode potential. Therefore, the titration end point can be determined according to the jump in the electrode potential.
      The manufacturer of Automatic Potential Titrator tells you that there are two parts of the instrument, the electrometer and the titration system. The electrometer uses an electronic amplification control circuit to compare the potential between the indicator electrode and the reference electrode with a preset end point potential. The difference between the two signals The value is scaled up to control the drop rate of the titration system. The titration stops automatically when the end point preset potential is reached. The manufacturer of Automatic Potential Titrator tells you that the instrument is controlled by a microcomputer, and its structure is divided into two parts: an electrometer and a titration system.
