| 摘 要： | 目前电导率测定在实验室是一个十分普遍而重要的项目,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。

| Abstract: | Conductivity determination is a common and important project, there are direct method and compare calibration constant electrode methods. Based on modern digital conductivity meter, the author designed a direct reading method in standard solution, by passing the step of conductance G （resistance）. This method is intuitive, simple operated, applicable to all the conductivity meters which need to be adjusted and read, and it need not calculate, saves time and manpower. |
