置。 A comparison electrode that selectively connects a sample injection port and a standard solution tank to a measurement flow path that is provided with an ion-selective electrode in the middle and in which liquid is fed by a pump, and that is provided with a reference electrode downstream of the ion-selective electrode. In an ion concentration measuring device in which a liquid flow path 9 is connected to form a liquid junction part, a pump control that detects fluctuations in the output from the electrode during standby and operates the pump when the output falls below a set level. A flow-through type ion concentration measuring device characterized by being equipped with a circuit.
