ABSTRACT:
An oxidation-reduction potentiometer immerses a working electrode and a reference electrode in a reference liquid, measures an interelectrode voltage between the above electrodes when an impedance reducing circuit is unconnected and an interelectrode voltage between the above electrodes when the impedance reducing circuit is connected by interelectrode voltage measuring means, computes a comparison coefficient based on the measured voltages by a comparison coefficient computing section, stores the coefficient in a comparison coefficient storing section, immerses the working electrode and the reference electrode in a test liquid, measures an interelectrode voltage between the working electrode and the reference electrode when the impedance reducing circuit is connected by the measuring means, and computes an oxidation-reduction potential by an oxidation-reduction potential computing section based on the measured voltage when the impedance reducing circuit is connected and the coefficient stored in the storing section.
