DEVICE FOR MEASURING THE ELECTROCHEMICAL POTENTIAL OF A STRUCTURE CONTAINING METAL, SUCH AS AN ARMED CONCRETE STRUCTURE, SUBJECT TO CATHODIC PROTECTION

摘要

The invention relates to a device (2) for measuring the electrochemical potential of a metal-containing structure, such as a reinforced concrete structure, which is subjected to a cathodic protection and which is at least partially immersed in water. water, comprising an isolation bell (4) open at a free end, said free end being intended, in measurement position, to come into sealed contact with the structure, a reference electrode (12) mounted inside the isolation bell and intended to come into contact with the structure when the insulation bell is in measurement position, and means (16) for discharging water and air enclosed inside the insulation bell when it is in the measuring position.
