VisiPro DO 225
產(chǎn)品介紹
貨號:243421
*根有防爆認(rèn)證的光學(xué)溶解氧氧電極
VisiPro DO 225是*的能夠用于防爆區(qū)域的光學(xué)溶解氧電極。
詳細(xì)介紹
光學(xué)測量原理改善了測量的性能,簡化了維護(hù)的程序。改善性能是相對于傳統(tǒng)的電化學(xué)(電流法)電極,不受流速的影響,快速啟動無需極化時(shí)間,維護(hù)十分簡單。
內(nèi)置變送器,電極可以直接和過程控制系統(tǒng)通過4~20毫安信號或者數(shù)字信號HART相連接。所有相關(guān)的數(shù)據(jù),包括校準(zhǔn)信息,診斷信息等都儲存在電極頭中簡化了校準(zhǔn)和維護(hù)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(shí)驗(yàn)室校準(zhǔn)、設(shè)置和維護(hù)程序。
為什么選擇VisiPro DO Ex?
簡化了校準(zhǔn)和維護(hù)程序:
