Claims

[Claims for Utility Model Registration] (1) An ion-selective electrode pair consisting of a solid electrode having an ion-selective layer on its surface that selectively responds to specific ions, and a reference solution and a sample in the ion-selective layer of the ion-selective electrode pair. a pair of liquid distribution members for supplying a liquid, and a pair of liquid distribution members for holding the liquid distribution member and the ion selection electrode pair therein, and for separately supplying the reference liquid and the sample liquid to the liquid distribution member. In an ion activity measuring instrument comprising a frame body provided with a supply hole and a bridge that electrically conducts the reference liquid and sample liquid supplied to the pair of liquid supply holes, the liquid distribution member formed by the frame body. An ion activity measuring instrument characterized in that an air vent hole is formed in the holding portion of the liquid distribution member at a position away from the liquid supply hole to communicate the holding portion of the liquid distribution member with the outside. (2) an upper frame body in which the frame body holds the ion selection electrode pair therein and is provided with a pair of liquid supply holes for separately supplying the reference liquid and the sample liquid to the liquid distribution member; The ion activity measuring instrument according to claim 1, characterized in that it comprises a lower frame body that holds the liquid distribution member therein. (3) an upper frame body in which the frame body holds the liquid distribution member therein and includes a pair of liquid supply holes for separately supplying the reference liquid and the sample liquid to the liquid distribution member; The ion activity measuring instrument according to claim 1, comprising a lower frame body that holds the ion-selective electrode pair therein.
