PRONOVA Ag/AgCl - reference electrode

The Ag/AgCl - reference electrode is an electrode with a defined and stable potential. It consists of a silver wire coated with silver chloride immersed in a 3 M KCl-filling solution (single bridge). The electrode is surrounded of a second electrolytic solution (double bridge) to avoid interfer-ence of the measuring solution by escaping silver and chloride ions of the filling solution.
