离子敏场效应晶体管PH电极

ISFET solid-state pH electrode

以美国利诺公司Durafet pH电极为例,介绍了工业在线用离子敏场效应晶体管（ISFET）固体pH电极的基本工作原理和结构;给出了温度、响应速度、稳定性、精度等主要技术指标的试验数据;指出了使用中应注意的一些问题。

The basic working principle and structure of ISFET solid-state on-line pH electrode are described using Durafet pH electrode as an example. Experimental data about the main performances of this electrode, such as temperature performance, speed of response, stability and accuracy are presented. Several problems about its application are dis-cussed.
