PROBLEM TO BE SOLVED: To provide a titration device capable of steady supply of a reagent by suppressing increase of a discharge pressure at the solenoid valve closing time, and thereby having improved safety. SOLUTION: This titration device is equipped with a measuring vessel filled with measuring fluid, a titration nozzle arranged oppositely to the measuring vessel, a titration solenoid valve having one end connected to the other end of the titration nozzle, a tube having one end connected to the other end of the titration solenoid valve, and a reagent tank connected to the other end of the tube, for supplying the titration nozzle with the reagent. The device is characterized by being equipped with the tube comprising soft material capable of absorbing pressure increase generated at the closing time of the titration solenoid valve by deformation expansion. |
