基于范德堡法的溶液电导率绝对测量方法
Absolute Measurement Method for Electrolytic Conductivity Solution Based on Van Der PauW Theory
摘要
Abstract
The application of Van Der Pauw theory to solution electrical conductivity measurement is proposed innovatively,a closed four-electrode conductivity cell is designed. A micro AC current source is used to provide excitation signals,control circuit is used to process signals and communicate with computer. A series of experiments are carried out to study the influence factors of Van Der Pauw method. The tests of the reference materials proved the measurement range of the method is 0~40 mS/cm,the measurement error is under ± 1%,which can be used for primary standard methods.关键词
