ABSTRACT:
An improved combination ion-selective electrode has a thin ion-sensing body extending from an outer reference body. The exposed portion of the ion-sensing body is encompassed by a sleeve which effectively forms an extension of the reference body and also provides mechanical stability to the ion-sensing body. One or more fluid channels are formed interior to the sleeve to provide an electrically conductive path from the reference solution within the reference body to the tip of the electrode.
