wtw ph計(jì)探頭wtw PH計(jì)電極由上海谷雨環(huán)?？萍脊?yīng)，全新，原裝，*。pH電極是zui為常用的電化學(xué)傳感器。同樣它提供zui靈敏的測量信號(hào)，需要定時(shí)保養(yǎng)和校正。IDS數(shù)字傳感器正是為了提高pH測量的精確性而設(shè)計(jì)的。
不受干擾的數(shù)字信號(hào)有2個(gè)好處，一是允許使用更長的電纜，另一個(gè)是可以同時(shí)傳輸校正數(shù)據(jù)和探頭ID識(shí)別碼 SenTix® | 940/940-3 | 950 | 980 | | pH | 0.000 … 14.000
