Product Description

cheap Aquarium DO online dissolved oxygen controller

Product Introduction
 

 

RD-20N dissolved oxygen analyzer is an online intelligent dissolved oxygen detector, we introduce the foreign technology, using imported components and dissolved oxygen membrane head, new polarographic analysis technology based on, and advanced production technology and surface mount technology. This series of advanced analytical techniques are used to ensure the stability, reliability and accuracy of the instrument over a long period of time. It has functions of Chinese menu, RS485 communication and so on. It can be widely used in chemical, fertilizer, metallurgy, environmental protection, water treatment projects, pharmaceutical, biochemical, food, aquaculture and tap water, such as continuous monitoring of dissolved oxygen value.
