This paper discusses the experimental results of measuring the electrical impedance of a liquid in a parallel position and perpendicular to the direction of the current injection. Experiments were conducted on three different types of liquids: aquades, mineral water and milk. Each liquid is placed in a cubic-shaped container having dimensions (2.5cm x 2.5cm x 2.5cm). Electrodes of a certain area are placed in the center of the vertical side of the container, so that two parallel plate pairs form, wherein one of the parallel plate pairs will serve as the current electrode. The range of current-signal frequencies used in this experiment is 1Hz-500Hz. From the results of experiments that have been done, obtained some things that is, each liquid used has different electrical characteristics, aquades is a solution with a much larger impedance compared with mineral water and then pure milk. The area of the electrode affects the measured impedance value of each liquid, the greater the electrode value of the liquid impedance value will decrease. The position of the electrode in the direction of the current injection shows the difference in the measured impedance value, where the measured liquid impedance at the current electrode of the current injection is greater than the measured value of the measured liquid impedance at an electrode perpendicular to the current injection.
