Description
Technical Field
The utility model relates to the technical field of potentiometric titrators, in particular to a constant-temperature potentiometric titrator.
Background
An automatic potentiometric titrator is a common analytical instrument designed according to the principle of potentiometry and used for volumetric analysis. The principle of the potential method is as follows: the proper indicating electrode and reference electrode are selected to form a working battery with the measured solution, and with the addition of titrant, the concentration of the measured ion changes continuously due to chemical reaction, so that the potential of the indicating electrode changes accordingly. In the vicinity of the titration end point, the measured ion concentration abruptly changes to cause a sudden electrode potential jump, and therefore the titration end point can be determined from the sudden electrode potential jump. The instrument comprises a distribution meter (controller) and a titration system, wherein the meter adopts an electronic amplification control circuit, the potential between an indicating electrode and a reference electrode is compared with a preset certain terminal potential, and the difference value of the two signals is amplified to control the dropping speed of the titration system. After reaching the end point preset potential, the titration is automatically stopped.
The height of the existing burette cannot be adjusted, the visual angle of a person can be adjusted only by moving the height of the human body downwards or upwards, the sight line is kept parallel to the concave liquid level, the titration reading is determined, and larger errors are easily caused.
