したことを特徴とする酸化還元電流測定装置。 A cathode is disposed inside a support tube having a filter attached to the lower end through which a sample liquid passes, an anode is attached to the outer surface of the filter, and an electrode main body having a solid electrolyte placed in the support tube, and the electrode. The main body has an insertion recess into which the main body is removably inserted, a sample liquid inlet connected to the recess at the lower part, and a sample liquid outlet connected to the recess at the middle part in the height direction, and the insertion recess a measurement cell in which, when the electrode body is inserted into the insertion recess, a sample flow path is formed between the electrode body and the peripheral wall of the insertion recess that communicates the inlet and the outlet; When a sample liquid is introduced into the measurement cell from the inlet with the electrode main body inserted into the cell, a part of the sample liquid flows into the support tube through the filter, and this sample liquid passes through the cathode and solid electrolyte. An oxidation-reduction current measuring device characterized in that the sample liquid is immersed in the sample liquid and the remainder of the sample liquid is discharged from the discharge port through the sample flow path.
