Summary:PURPOSE:To use a titled apparatus in a maintenance-free state for a long period, by sending a sample solution, a standard solution, and a regenerating liquid of an ion selective electrode to a cell room selectively. CONSTITUTION:Only standard solutions 6 and 6' are sent to a cell room 1 by actuating a liquid sending pump 10 and operating sending liquid switching means 8 and 8' and an ion selective electrode 2 is calibrated. Next, only a sample solution 5 is introduced into the room 1 by switching the means 8 and the ion concentration is measured. Next, only a regenerating liquid 7 is introduced into the room 1 by switching the means 8 and 8' and is allowed to stand in the room for a prescribed time and then, regenerating treatment of the electrode 2 is carried out. This liquid 7 is a plasticizer of the same kind as that for constituting an ion selective film of the electrode 2.
