Installation for measuring the radio engineering characteristics of dielectric materials in the temperature range from 20 ºС to 400 ºС MREC-400
Designed for
measurements of relative dielectric permittivity and tangent of dielectric loss angle of materials in the temperature range from 20 ºС to 400 ºС.
The installation implements the cavity method by GOST R 8.623-2015 "GSI. Relative dielectric permittivity and dielectric loss tangent of solid dielectrics. Methods of measurements in the microwave band». A feature of the installation is the heating of only the measured sample and one cavity wall, which provides a quick exit to the mode and low power consumption. Connection to local exhaust ventilation is provided to remove the heating products of the measured samples.
