SILVION is the UKís leading designer, manufacturer and supplier of Silver/Silver Chloride (Ag/AgCl) reference electrodes for use in the cathodic protection (CP) industry and was established in April 1984 by an Electrochemist/Corrosion Scientist with considerable experience in the use and manufacture of Silver electrodes in the corrosion and battery ndustries.SILVION are proud of the fact that our reference electrodes have been used in concrete Cathodic Protection systems since 1985. Ag/AgCl reference electrodes are one of the key elements for the prevention of rebar corrosion in concrete and constitute the performance monitoring system for cathodic protection installations. Silvion electrodes are robust and have been specifically designed to allow permanent embedding in concrete. Our long life electrodes are suitable for high alkaline or chloride condition concrete and can be used for the monitoring of rebar/electrolyte potentials or for the control of DC power supplies. Applications include concrete Bridges, Seawater Intakes, Marine Structures, Buildings and Cooling Water Towers. Over the past 25 years Silvion has supplied over 60,000 various Ag/AgCl reference electrodes to projects in the UK, Europe, Middle East, North Africa, South Africa, Asia, New Zealand, USA & Canada.
