PROBLEM TO BE SOLVED: To provide an electrochemical measurement apparatus capable of continuously performing electrochemical measurement to fluid.SOLUTION: An electrochemical measurement apparatus 1 is equipped with: a pipeline 2 which constitutes a circulation path for taking out slurry from a bottom part in a container 11 and returning it to an upper part in the container 11; a pump 3 which is provided for the pipeline 2 and is used for transporting slurry; a pair of electrodes 4,5 provided in the pump 3; and an electrochemical measurement instrument 6 to which the electrodes 4,5 are connected. The pump 3 is a uniaxial eccentric screw pump, and includes a cylindrical stator 31 and a rod-like rotor 32 engaged in the stator 31 in an eccentric rotatable manner. The pair of electrodes 4,5 are attached to an area near a discharge port 35a of the stator 31. The surfaces of the electrodes 4,5 are exposed to the internal space of the stator 31 and face to each other. |
