A device for measurement of humidity includes a sweep oscillator, analog-digital converter, detector, coaxial resonator, beyond-cutoff section, excitation loop, sectionalizer, sample of material under investigation, sealing insert, tightening spring, detector loop, micro-processor system, indicator. The sectionalizer is in the beyond-cutoff section, with separating it from the sample of material under investigation, the sample under investigation is placed outside the beyond-cutoff section. The working frequency of the coaxial resonator is changed in the process of measurement of humidity to obtain a set of values of q-quality and resonance frequency. |
