电磁感应原理在检测分析仪表中的应用——日本DKK公司无电极电导率计及无电极酸碱盐浓度计

摘要

本文介绍了日本DKK公司利用电磁感应原理制造的无电极电导率计及无电极酸碱盐浓度计。本文列出了H2SO4、HNO3、HCL、NaOH、NaCl溶液浓度对电导率的二维相关曲线；H2SO4溶液浓度对电导率和温度的三维相关曲面；以及DKK公司无电极酸碱盐浓度计与其他公司同类产品浓度测量范围比较表。%This article presents both electrodeless conductivity analyzer and electrodeless concentration analyzer for testing acid,alkaline and salt solutions,which are made by the japanese DKK Corp.in accordance with an electromagnetic induction principle.The paper also illustrates the two-dimensional correlation curves of the concentration of H2SO4，HNO3，HCL，NaCH,NaCl solutions vs the conductivity,and the three-dimensional correlation curved surface related to the concentration of H2SO4 solution,conductivity and temperature,along with a comparasion table provided with concentration measuring ranges of the same type products from other companies as the said concentration analyzer from the DKK Corp.
