An apparatus and method for measuring conduction current through a sample portion of the surface of the solid conductor that is in contact with a liquid conductor, such as the solid electrolyte of a liquid-solid-liquid battery, is provided. The apparatus includes a probe having a hollow insulating probe body with an interior adapted for holding a small amount of the liquid conductor. The probe body insulates the probe liquid conductor from the surrounding liquid conductor and includes a tip having an opening in communication with the probe interior. The tip is adapted for making sealed contact with the solid conductor surface. The conduction current through the sample area can thereby be isolated and measured. The method for measuring conduction current through the sample area includes providing the probe, positioning the probe tip in sealed contact with the solid conductor, disposing a probe liquid conductor within the probe interior, conducting a current through the probe liquid conductor and the sample area and measuring the probe current.
