JH180 The automatic polarimetric titrator has⑴ Polarization，(2) Depolarization titration function。

Polarization, depolarization titration and determination of end point of solution are commonly used methods for volumetric analysis of substance content.

The indicator electrode of this instrument is double platinum electrode.

1. Polarization titration, before titration, the electrodes have electrical signals in the solution. When the titration reaches the end point, the electrodes have no electrical signals (or small electrical signals). The end point of the solution can be judged by the instrument through the change of electrical signals.

2. In depolarization titration, there is no electric signal (or micro-electric signal) in the solution before titration. When the titration reaches the end point, the electrode has electric signal. The end point of the solution can be judged by the instrument through the change of electric signal.

Titration is completed when the changed electrical signal is stable (meeting the delay time). The instrument automatically terminates the titration, indicating that the titration has been completed.

The instrument automatically identifies the direction of titration, judges dripping and non-dripping, judges the end point of titration, and displays the end point current value.

Instruments are widely used in pharmaceutical, chemical, petroleum, lightening, food and many other industries and disciplines. It can be used for solution analysis of various polarization and depolarization titrations.
