Abstract: The present invention relates to a measuring device (10) of the electric properties of solid or liquid geological samples, such as, for example, rocks, preferably from oil or gas reservoirs, and saturation fluids of the same, comprising a hollow body (11, 12) consisting of a first upper half-shell (11) and a second lower half-shell (12), the upper and lower half-shells (11, 12) coaxially sliding one inside the other, inside the body (11, 12) there being a housing seat (23) for a substantially cylindrical sample, two pairs of electrodes (13, 14) being envisaged facing the housing seat (23) for the injection of current into a sample and for the measurement of the voltage at the ends of the sample, characterized in that the pairs of electrodes (13, 14) are pairs of coplanar electrodes, each situated at one end of the housing seat (23).
