Dielectric Spectrometer

Dielectric Spectrometer/DETA

The Dielectric Thermal Analyzer (DETA) is used to measure the magnitude of impedance and phase angle. From these measurements, it is possible to calculate resistance, capacitance and other frequency dependent values of different materials. The impedance analyzer applies a current across the sample through the relationship IR=V. This provided an applied voltage in frequency across the sample. By taking a 4-point probe measurement, the analyzer is able to gather values for the magnitude and phase angle as a function of frequency.
