The electrodes have glass membranes and incorporated external reference system. The connection of the glass membrane with coaxial cable is carried through a liquid contact. Coaxial cable is typically ended by BNC connector. The external Ag/AgCl reference system is incorporated in the outer part of the body of electrode. The external reference electrode is filled by 1 M KCl. The electrode body is made of a low leach glass with high chemical resistance against the majority of normally used chemicals. Typical length of body is 145mm.
