Dissolved oxygen water quality on-line analyzer
Model：ERUN-SZ1-A-A5
Dissolved oxygen DO (polarography)
Online dissolved oxygen meter is an online intelligent dissolved oxygen detector produced by our company by introducing foreign technology, adopting imported components and dissolved oxygen membrane head, based on polarographic analysis technology, and advanced production process and surface paste technology.The use of this series of advanced analytical techniques ensures that the instrument works stably, reliably and accurately for a long period of time. With Chinese menu operation, notepad storage of measurement data, 485 communication and other functions.Widely used in continuous monitoring of dissolved oxygen value in solution of chemical fertilizer, metallurgy, environmental protection water treatment engineering, pharmacy, biochemistry, food, breeding and tap water.
