Abstract
An ion selective electrode apparatus for measuring ion activity of solution flowing through a conduit, wherein at least one earth electrode is disposed so as to contact the solution. The earth electrode is capable of shunting electrical noise flowing through the conduit to earth. In the preferred embodiment, an ion selective electrode and a reference electrode are disposed along the conduit between two earth electrodes so as to protect the ion selective and reference electrodes from the electrical noise which may be introduced into the ends of the conduit.
