ref·er·ence e·lec·trode

an electrode expected to have a constant potential, such as a calomel electrode, and used with another electrode to complete an electrical circuit through a solution; for example, when a reference electrode is used with a glass electrode for pH measurement, changes in voltage between the two electrodes can be attributed to the effects of pH on the glass electrode alone.

reference electrode

A chemical electrode whose cell potential remains fixed and against which an indicator electrode is compared. The most common reference electrode is the silver/silver chloride (Ag/AgCl) electrode.

The diameter of the exposed working electrode, reference electrode, and counter electrode area in the prepared screen-printed electrode was 0.2 cm, 0.1 cm, and 0.48 [cm.sup.2], respectively.
The five main sensor components are the sensor body, measuring electrode, reference junction, temperature sensing element, and reference electrolyte.
First step includes sample information which concerns the pH of standard buffer solutions, number of buffer solutions used to verify pH electrode, reference of pH combined electrodes or two separate electrodes and sample solution temperature.
