1. A device for measuring an electrical property of a conduit, wherein the conduit is arranged in a submerged or subterraneous environment and is surrounded by an insulator layer, wherein the device comprises:
a first electrode;
a mounting unit configured to be arranged on a surface of the conduit and to create an enclosure against the surface, said enclosure containing the first electrode and configured to form a dielectric between the first electrode and the environment;
a second electrode configured to be arranged at a distance of the surface and at a distance of the first electrode, wherein the second electrode is intended to be in contact with the environment; and
a measurement instrument configured to determine a value which is representative of an impedance between the first electrode and the second electrode.
