internal reference electrode

An 'inner' reference electrode which is contained inside an ion-selective electrode assembly.
Note:
The system frequently consists of a silver/silver chloride electrode in contact with an appropriate solution containing fixed concentrations of chloride and the ion for which the membrane is selective. This 'inner' filling solution is in contact with the ion-selective membrane.
