The permanent reference electrode Cu/CuSO4 with two coupons CuRE 2.0 is a new generation device for cathodic protection monitoring of underground metallic structures, in accordance with UNI EN ISO 15589-1.
The electrode potential is given by a copper element in contact with an electrolyte made of saturated copper sulphate gel. The two coupons, once connected to the cathodically protected structure, allow to measure the absorbed current and verify AC/DC interference, if any. The electrode is an innovative product covered by an Italian patent.
