EXAxt SC450系列专用于由微型计算机(PDA)支持的、Yokogawa EXA系列简单易用的优秀功能组合。
EXAxt SC450真正独特之处在于其人机界面。高分辨率图解显示和触摸屏操作，使所有的信息操作者都能看见。与触摸屏组合，就像操作PDA一样简单。语言选择简单及屏幕指示，可确保获得最佳应用组合。
EXAxt SC450提供mA输出或触点输出上PID控制的所有功能。
触点输出可选择为脉冲频率控制或脉冲长度控制功能，以便控制化学计量泵或电磁阀。
EXAxt SC450是一款智能分析仪系列：两个mA输出一个数字HART信号叠加在mAl上。该信号可提供最多4个过程变量及许多诊断数据。该信息可用来形成辅助电流及HMI监视器中有触点输出，以及如PRM或AMS这样的维护优化程序。软件包可从Yokogawa网页上下载，使用户能将SC450与PC组合。
通过将电导率测量与先进的温度补偿功能和预装的校正标准程序及电导池结垢监测组合，SC450可提供最佳的精度。
EXAxt SC450足通用型的。分析仪可接受电极常数从0.005～50cm-l的传感器；可接受2一电极传感器和4一电极传感器；5个不同的温度补偿元件确保了精确的温度补偿。
SC450提供除盐水、蒸汽、冷凝和锅炉水分析（阳离子电导率、氨和吗啉电导率）的超纯水温度补偿（缺省：NaCL）。
SC450也提供矩阵补偿并线性化输出，用于强酸、强碱，特别是在制药工业的超纯水监测

Project database
All configured signals, variables and process points are in Freelance
800F system’s public database for management.
● List of all variables (input, output, internal variables)
● Process point list (function block)
●Graphics
●Program
Because the database is system-wide. The data only needs to enter a
times, to avoid possible errors caused by multiple configurations.
Project database files can be easily archived or backed up.
When programmed by the user, a list of variables and labels is automatically created.
Moreover, both variables and process points can be opened and closed directly in FBD or IL

List other features include:
Project-wide modification of names, comments, data or module types
●Search and display based on specific criteria
● Cross reference can be used in systems that use a large number of variables or process points
