Cathodic Protection Reference Electrodes
Nuref designs, manufactures and supplies high-performance reference electrodes for monitoring cathodic protection on pipelines, marine structures and reinforced concrete.
Selection depends on the electrolyte your structure sits in and how long the electrode must stay in service — our engineers confirm against your survey data.
