Abstract

Device for electrochemical corrosion monitoring (1) of an on-site conductive material (5) comprising at least two compartments (2), each of the compartments is suitable to form an electrochemical cell and comprises two valves (31, 32) being respectively positioned at a upper face (41) and at a lower face (42) of the device, each of the valves being arranged to selectively close and open the upper face or the lower face of its respective compartment so that each compartment is selectively, partly or fully, seal from or, partly or fully, connected with the outside of the compartments. The device (1) comprises a reference (6), or pseudo-reference electrode, and a counter electrode (7), or an auxiliary electrode, disposed in each compartment. The device (1) is suitable to be fasten on the on-site conductive material so that a surface (8) of the on-site conductive material forms at least a part of an inner surface (9) of each of the compartments and form a working electrode (9) of each compartment. The device (1) further comprises means (10) arranged to carry out electrochemical measurements, from the reference, the counter electrode and the working electrode of each compartment, and to determine corrosion rates of the on-site conductive material from the electrochemical measurements.
