电导率仪用于测定液体的电导率,由于其操作简便、快捷、测量范围广,因而被广泛使用。在实验室中,常用电导率仪测定已知浓度的弱电解质溶液的电导率从而计算其电离常数。在工厂中,常用电导率仪进行水质检测。配以适当的组合单元,还可达到自动记录和自动控制的目的。液体的电导率也可采用电导仪测定。其方法是:先测定已知浓度的 KCI 标准溶液的电导,标 Conductivity meter used to determine the conductivity of liquids, because of its easy to operate, fast, wide measuring range, it is widely used. In laboratories, the conductivity of a weak electrolyte solution of known concentration is often measured using a conductivity meter to calculate its ionization constant. In the factory, commonly used conductivity meter for water quality testing. With the appropriate combination of units, but also to achieve the purpose of automatic recording and automatic control. Conductivity of liquids can also be measured using a conductivity meter. The method is: first determine the concentration of known KCI standard conductivity, standard
