In an apparatus for measuring a property of a dielectric material, electrical signals at different respective frequencies from two sources 10, 12 Fig. 2 are supplied to the material 11 by the electrodes 27, 29 of a probe 28, separate signals each influenced by the property to be measured are derived by filters 42, 44, from the probe and combined to produce a continuous resultant signal that is a function of the ratio of the magnitudes of the separate signals, and the output from one of the sources 12 is arranged to be controlled in response to deviations in the average value, a motor 52 which effects the control being arranged also to operate means 56 for indicating the measured value and temperature compensation being provided. The oscillator outputs are applied through input impedances 16, 18, and a feedback amplifier 20 of unity gain and not including tuned circuits, to a differential circuit including the probe, the amplifier serving as a summing amplifier and preventing one source from loading the other. The lower path of the differential circuit includes a phase inverter 24 and an adjustable capacitor 32, this latter may be equal to the test probe capacitance in the balanced condition or may be of a value determined by the relative impedances of network 26 and the phase inverter. The difference in output of the two signals S H , S L  derived from unbalance in the differential circuit is used to control wipers 14H, 14L in the output of LF oscillator 12 to maintain the desired ratio, temperature compensation being provided by a potentiometer 68 driven by motor 78 in responses to changes in the temperature of a thermistor 72.
