The 13 pages that link to Reference electrode, each with the reason it gives.
ElectrodeBroader topic: It provides a comparison point when characterizing an electrode's voltage.
PotentiometryRelated: Its stable potential provides the baseline for the measured cell voltage.
CoulometryRelated: Controlled-potential coulometry uses it to set the working electrode potential.
Cyclic voltammetryRelated: The applied scan is defined relative to this stable potential.
VoltammetryRelated: It anchors the applied potential so voltammetric measurements are comparable.
ElectrosynthesisRelated: It allows reaction potentials to be reported and controlled reproducibly.
