VisiPro DO 120

產品介紹

貨號：243420

*根有防爆認證的光學溶解氧氧電極

VisiPro DO 120是*的能夠用于防爆區域的光學溶解氧電極。

光學測量原理改善了測量的性能，簡化了維護的程序。改善性能是相對于傳統的電化學（電流法）電極，不受流速的影響，快速啟動無需極化時間，維護十分簡單。

內置變送器，電極可以直接和過程控制系統通過4~20毫安信號或者數字信號HART相連接。所有相關的數據，包括校準信息，診斷信息等都儲存在電極頭中簡化了校準和維護的程序，附加的無線通訊功能可以使電極直接和你的電腦相連接，簡化了實驗室校準、設置和維護程序。

為什么選擇VisiPro DO Ex？

簡化了校準和維護程序:
