Device and method for measuring the electrical conductivity of highly insulating liquid.; The present invention relates to a device and method for measuring the electrical conductivity of highly insulating liquid. The device comprises a movable upper electrode vertically divided into two electrically isolated regions, guided by a mechanical structure which ensures the parallelism and driven by a motor for controllably varying the distance between electrodes, and a lower electrode shaped vessel containing the liquid sample. The proposed method is characterized by applying potential differences for a fixed spacing between electrodes, applying each value of the potential difference to reach the steady state in each period and measuring electrical currents produced at steady state.; The present invention has its application in the chemical industry to control the purity of aislanteso liquid to control the stability of colloidal suspensions high application (for example, paints or printing inks).; It is also necessary to control the conductivity of jet fuels to prevent the occurrence of high voltages during flow.
