internal reference electrode
An 'inner' @R05229@ which is contained inside an @I03244@ assembly.
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 @MT06878@ is selective. This 'inner' filling solution is in contact with the ion-selective @MT06878@.
