摘要

FIELD: agriculture; food industry; fishing industry. ^ SUBSTANCE: samples are prepared from objects of test. Conductivity-measuring cell is filled with the samples. Value of phase shift between input voltage, applied to input of cell, and output voltage, read out from output of conductivity-measuring cell of phase analyzer is measured. Content of sodium chloride in analyzed sample is determined from preset calibration of phase shift value depending on content of sodium chloride. ^ EFFECT: improved precision; improved sensitivity. ^ 3 tbl, 3 dwg
