Silver/silver chloride (Ag/AgCl) electrodes are available in two primary forms: for laboratory electrochemistry and surface electrodes (sintered or disposable) for medical and biopotential monitoring. 1. Laboratory Reference Electrodes
These are reusable probes used in pH measurement, titration, and voltammetry. They typically consist of an AgCl-coated silver wire in a glass or plastic body filled with potassium chloride (KCl). StonyLab Ag/AgCl Reference Electrode silver silver chloride electrode buy

These are used for recording biological signals like EEG, ECG, and EMG. Ag/AgCl is preferred here for its low noise and non-polarizable nature.
