Abstract: A measurement electrode head system is disclosed for connection to electrodes for electrochemical potential measurement. The head includes an electrode cap for connection with glass and plastic electrode rods. A coaxial cable having an outer shielding conductor and an inner conductor connects to the cap. A plastic jacket is integrally molded onto one end of the coaxial cable. The jacket has a continuous electrically conductive shielding layer adjacent an inside surface thereof and the inner conductor of the cable connects with a connection element supported within and surrounded by the electrode cap and conductive shielding layer.
