Abstract
In order to measure a complex dielectric constant, a sample 8 enveloped by a ring 9 and two laminas 10 is inserted between parallel plate electrodes constituted by an exciting electrode 2 and a response electrode 3. Measuring data is obtained as a measuring value of the sample 8 itself because an operational circuit 21 removes parasitic effects of the ring 9 and the lamina 10. Dielectric characteristics of a fluid sample can be obtained readily and accurately without contaminating the electrodes.
