CROSS CAPACITOR ELECTRODE TEST TUBE, DEVICE AND METHOD FOR MEASURING DIELECTRIC CONSTANT OF LIQUID

摘要

PURPOSE: A cross capacitor electrode test tube, a device and a method for measuring a dielectric constant of liquid are provided to repeatedly measure the dielectric constant of measured liquid without a measuring error by a chemical reaction between an electrode and the measured liquid and to minimize a generation of error according to a washing of the measurer. CONSTITUTION: A dielectric constant measurer(21) of a liquid dielectric comprises devices as follows. A chamber(22) has a first hole(26) on an upper plate(24). A metal cylinder(28) is inserted in the first hole(26). An electrode test tube is inserted in the metal cylinder(28) to conform a central shaft. A measuring terminal(30) is connected between electrodes to measure capacities between a first electrode(12) and a center electrode(14b) and between a third electrode and a center electrode(18b) by an external capacity measurer.
