摘要
研制了酸度在线检测装置，并应用于溶液酸度在线检测。溶液酸度在线检测装置，设有防污过滤器、自动采样器、蠕动泵、小型管道ｐＨ传感器和控制电路等。其特点为可防污除油、随机自动采样、定时检测、全部管道化、可单独使用或和计算机控制系统联网，适用于溶液酸度在线分析。测定精度＜ｐＨ０．
An on line pH detector has been developed.The device is composed of a sampling head,a peristaltic pump,a flow through pH detector and control circuit.The device can perform pH detection automatically.It can work either indepentently or be connected with and controled by central control computer.The device has already been applied to the industial production line for the extraction separation of rare earth elements.The detection circle is 2 min and the precision of detection is less than pH0.05 .
