Abstract

A rapid precise method for measurement of the dielectric constant of liquids in a wide frequency range is described. Using a micrometer‐controlled electrode in a cell filled with the specimen liquid, the dielectric constant is precisely determined from the micrometer scale to within ±0.2%. Even though the cell is two‐terminal, this method is nearly free of the influence of the stray capacitances and the residual inductances of the electrodes or of the leads. It makes possible an accurate measurement at high frequency. Once the micrometer scale calibration has been done, it takes only a few minutes for the measurement. The measured frequency responses of the dielectric constants of several compounds are also shown in this paper.
