ABSTRACT:
In a titration controlling method and apparatus wherein variations of a titration system caused by intermittent titrations are successively detected electrically, and the quantity of each intermittent titration is controlled by an electric signal obtained by the detection until an end point is reached. According to the present invention, the quantity of each intermittent titration is determined by dividing the quantity of the immediately prior titration, which has been memorized, by the variation of the titration system caused by the immediately prior titration.
