ABSTRACT:
An improvement of a device for measuring ion activity in a liquid sample comprising at least a pair of ion-selective electrode sheets, liquid-guiding portions for guiding a reference liquid and a liquid sample to each active surface of the pair of ion-selective electrode sheets respectively, and a bridge for electrically connecting both liquids supplied on the electrode sheets to each other is disclosed. Each ion-selective electrode sheet is arranged in such a manner that the active surface of the ion-selective electrode is placed upside down and each liquid guiding portion comprises a horizontal passage for conveying the liquid sample or the reference liquid supplied from the outside in the horizontal direction to the position just below the active surface of the ion-selective electrode, the horizontal passage being formed in a lower position than the active surface of the ion-selective electrode; and the horizontal passage is provided with a porous distributor which is bent to protrude upwardly from the horizontal passage up to the position just below the active surface of the ion-selective electrode so that the liquid sample or the reference liquid conveyed to the porous distributor can be brought into contact with the active surface of the electrode.
