Product Description

RS485 Online Optical Dissolved Oxygen Sensor

RS485 Online Optical Dissolved Oxygen Sensor

Product Introduction
A10 dissolved oxygen meter 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 stabilityreliability and accuracy of the instrument over a long period of time. It has functions of Chinese and English 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 watersuch as continuous monitoring of dissolved oxygen value.
