Abstract

Results of the uncertainty analysis of the error-corrected permittivity measurements of materials using open-ended sensors are reported. Uncertainties in the permittivities of the reference liquids due to the uncertainties in the Cole-Cole parameters are discussed. The effect of the selection of these parameters of reference liquids, when used as calibration standards for error-corrected permittivity measurements, is highlighted. The results of measurements performed on 15 and 30 ppt saline test liquids are presented along with the measurement uncertainties resulting from uncertainties in the Cole-Cole parameters of the reference liquids
