Abstract
PURPOSE: To prevent excessive titration, by controlling the titration in such a manner as to slow down toward the end.
CONSTITUTION: A titration liquid is put into a titration cell 1 and the titration is commenced. An electrical signal matching concentrarion of a prescribed substance contained in the liquid being titrated is emitted from a detection electrode 3 and put into subtractor 6, and output of an ending potential setter 5 is reduced. The output is put into a converter 8 through a potentiometer 7. In this converter 8, it is converted to an output pulse of a frequency proportional to the input and impressed onto a pulse motor 9 through a frequency divider 11. And therefore, the pulse motor 9 is driven at the speed matching change in condition of the liquid in titration, and it slows down toward the end of the titration, and when output of an amplifier became equal to that of the ending potential setter 5, output of the subtractor reducer 6 becomes zero, the pulse motor 9 is stopped and the titration is completed.
