平度光学溶解氧氧电极-VisiPro DO 120-瑞士Hamilton

货号：243420

全球第一根有防爆认证的光学溶解氧氧电极

VisiPro DO是唯一的能够用于防爆区域的光学溶解氧电极。

VisiPro DO光学测量原理改善了测量的性能，，简化了维护的程序。改善性能是相对于传统的电化学（电流法）电极，，不受流速的影响，，快速启动无需极化时间，，维护十分简单。

内置变送器，，VisiPro DO电极可以直接和过程控制系统通过4~20毫安信号或者数字信号HART相连接。所有相关的数据，，包括校准信息，，诊断信息等都储存在电极头中简化了校准和维护的程序，，附加的无线通讯功能可以使电极直接和你的电脑相连接，，简化了实验室校准、设置和维护程序。

为什么选择VisiPro DO Ex？

简化了校准和维护程序:
