PROBLEM TO BE SOLVED: To further improve the speed and accuracy of titration by controlling the drop feed of a titration liquid using a control function based on at least one differential constituent. SOLUTION: A middle memory M1 retains a signal value at a certain time from a signal that is generated by a platinum electrode 16 being inserted into a titration container 15 where a titration liquid is supplied and then a corresponding differential constituent is determined by a differential stage 20. A processorμwhere it is inputted questions a different differential constituent (a titration curve) that a memory M2 stores at each point halfway through the setting and functions as a comparator. A fuzzy theory module Fuz inputs information regarding distance to an end point from a titration curve at a certain time and information regarding a value at a certain time of the differential constituent from the microprocessorμ. Also, additional data is also inputted from each keyboard of a titration device 10 via a signal line 21. Then, an input signal is connected and a corresponding control signal is sent to the titration device 10 via an output line 22, the rhythm of a pump for supplying to the titration container 15 is adjusted, and the maximum amount that is a control variable is adjusted, thus controlling the drop feed of the titration liquid. |
