The invention relates to a high-frequency-based measuring device (1) for determining a dielectric constant of a medium (2), comprising the following components:-a signal generating unit (11) for coupling an electrical high-frequency signal (sHF) into an emission electrode (12) located in the medium (2) for emitting a high-frequency signal (sHF) having a depth (h) of at most one fourth of a wavelength (lambda) of the high-frequency signal (sHF); -a receiving electrode (13) likewise located in the medium (2) and located at a distance (d) from the transmitting electrode (13), the distance (d) being at most one fourth of the wavelength (lambda) of the high-frequency signal (sHF), in order to receive the high-frequency signal (sHF) after the high-frequency signal (sHF) has passed through the medium (2); and an evaluation unit (14) which is designed to determine the dielectric constant on the basis of the received high-frequency signal (sHF). As a result of this sizing and positioning of the electrodes (12, 13) wit
