Apure A10 digital aquaculture water do online optical dissolved oxygen meter with sensor 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 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 water, such as continuous monitoring of dissolved oxygen value.
Characteristics:
- Large screen dot matrix LCD display, English menu operation.
- Multi parameter simultaneous display: oxygen value, temperature, output current, alarm point and so on. Visually readable and with range overrun hints.
- The alarm status is displayed on the screen, and the output of the switch ON signal can be simultaneously connected.
- Communication function (optional): RS-485 communication interface (MODBUS Protocol Part compatible), 4-20 mA current output corresponding to the DO value can be arbitrarily set
- Arbitrary setting function of hysteresis, Avoid frequent action of switch and relay.
- Watchdog function: Make sure the instrument does not crash.
- The core components come from famous foreign brands.
