摘　　要：An easy and practical system of feeble fluctuation of liquid electrical conductivity is described. The system, which increases a precision on the three orders magnitude as compared with that of the recent domestic conductivity meter, is used to measure the feeble fluctuation of the conductivity by means of compensation and comparison, so that it solves the problem of measuring the feeble fluctuation.An easy and practical system of feeble fluctuation of liquid electrical conductivity is described.
