A three-terminal cell similar to that described by Hartshorn et al. was constructed. The cell consists essentially of two coaxial platinum cylinders 0.2mm thick, the inner one having a diameter 18.4mm and the spacing between their walls being about 1.3mm. The electrode assembly is mounted within a double-walled cylindrical cell made of Pyrex Glass. The cell capacitance was measured with a capacitance bridge (General Radio Co., Type 1620), which is 26.5650±0.0005pF. The required amount of liquid for dielectric constant measurements is about 50ml. The dielectric constants ε of benzene and cyclohexane were measured at a frequency of 10kHz in the temperature range of 25° to 55℃. The results obtained are as follows, ε=2.27410-0.00197(t-25) (benzene), ε=2.01477-0.00157(t-25) (cyclohexane). where, t is the temperature in ℃. These values are in good agreement with the standard values reported by NBS.
