A method for measuring an electrical conductivity of a medium with a conductive conductivity sensor with four electrodes includes measuring a first impedance dependent on a first total impedance of the first voltage electrode and a medium layer adjacent to the first voltage electrode, measuring a second impedance dependent on a second total impedance of the second voltage electrode and a medium layer adjacent to the second voltage electrode, and making a conductivity measurement using an alternating electrical signal introduced into the medium via the first current electrode and measuring a potential difference between the first voltage electrode and the second voltage electrode. Based on the measured potential difference, the first impedance, and the second impedance a corrected potential difference is determined. Based on the corrected potential difference, a measured conductivity is determined.
