We perform measurements of dielectric properties (electrical conductivity and permittivity) in frequency range from 4 MHz to 3 GHz with Dielectric Assesment Kit (DAK) from company SPEAG (Switzerland) with probe DAK12. DAK is suitable for measurement of dielectric properties of biological tissues or their phantoms.

Furthermore, we own a probe for measurement of dielectric properties of low loss liquides in frequency range from 10 MHz to 3 GHz. The probe is equiped with heat exchanger and it is therefore possible to change temperature of the measured samples in range from 10 to 70 °C [1, 2]. The in-house developed procedures are used to create temperature and frequency dependent mathematical models of dielectric properties of the measured liquids.

Measured data is delivered in the form of a measurement protocol and is supplemented by information about measurement uncertainty.
