[Low-frequency conductometry of the tissues and organs of undefined geometrical form].
The authors review potentialities of the use of the four-probe methods for measuring specific electric conductivity (SE) on biological objects. An analysis was made of the main causes of the method limitations and occurrence of errors during low-frequency measurements. As a result a design of a four-electrode conductometric set up is suggested with a purpose of measuring SE of biological objects of undefined geometrical form with a high accuracy of measurements at low frequencies. The positive effect was attained at the expense of reducing the impedance of potential electrodes at low frequencies.
