Silvion was established in 1984 by Dr S Pathmanaban, a considerably experienced electrochemist and corrosion scientist with a Ph.D from the University of Manchester. This education provided the platform for Dr Pathmanaban to develop a business based on the design and manufacture of ‘Silvion’ reference electrodes for use in Cathodic Protection (CP) systems. Since then, Silvion has gone on to develop a whole range of silver/silver chloride (Ag/AgCl) reference electrodes to meet industry demand, and continues to manufacture all of its products in the UK at its current facility in Grantham, Lincolnshire.


​Silvion is renowned worldwide by engineers in the Corrosion Prevention Industry and takes pride in offering clients top quality products that include the latest advances in reference electrode technology. Our products provide accurate and reliable monitoring and control of CP systems for Onshore/Offshore Oil & Gas, Petrochemical, Power and Water industries and for Marine and Concrete Structures.
