摘　　要：目前电导率测定在实验室是一个十分普遍而重要的方法,标定电极常数的方法有直接测定法和比较测定法。在直接测定法的基础上,针对现代数显电导仪的特点,设计了标准溶液直读法标定电极常数,绕过了标定过程中需要测定电导G(电阻)的步骤。该方法直观易懂,操作简单,不需要计算,省时省力,适用于所有需要调节并能读出该电极常数的电导率仪。At present,measuring conductivity for some experiments in the laboratory is a very common and important method.Calibration constant electrode method has direct method and compare assay.Based on the characteristics of modern digital conductivity meter in the direct method,a method for electrode constant through reading the standard solution is designed,bypassing the step of determining conductance G （resistance）.The method is easy to operate,and isn＇t need to calculate.The method is applicable to the conductivity metes which need to be adjusted and are able to read the constant of electrode.
