An electrochemical electrode has a screened cable 11 electrically connected to it and a further screen 17 enclosing at least a major part, but not all, of the electrode itself, the latter screen in turn being electrically connected to the cable screen. The electrode screen may be spaced by a small axial distance from the cable screen and connected to it by a separate axial link. The screen is preferably of steel, aluminium or mumetal coated on one or both of its faces with a non-conductive coating. The electrode may be a pH electrode, an ion-specific electrode, a glass electrode or a micro referecence electrode. <IMAGE> |
