2. Product introduction

XG-9800 dissolved oxygen meter is an online intelligent dissolved oxygen detector produced by our company introducing foreign technology. It adopts imported components and dissolved oxygen membrane head, based on the latest polarographic analysis technology, and advanced production technology and surface mount technology. . The use of this series of advanced analytical techniques ensures long-term stability, reliability and accuracy of the instrument. It has functions such as Chinese menu operation, notepad storage of measurement data, and 485 communication. XG-9800 dissolved oxygen meter can be widely used in continuous monitoring of dissolved oxygen value in chemical fertilizer, metallurgy, environmental protection water treatment engineering, pharmaceutical, biochemical, food, aquaculture and tap water.

Main features of XG-9800 dissolved oxygen meter:

◇Large-screen dot matrix liquid crystal display, Chinese menu operation.

◇ Simultaneous display of multiple parameters: dissolved oxygen value, temperature, output current, alarm point, etc. are displayed at the same time, which is intuitive and easy to read, and has a range overrun prompt.

◇The screen displays the alarm status and can be accompanied by switch ON/OFF signal output at the same time.

◇ Automatic temperature compensation function: automatic 0 ~ 60 ℃.

◇Communication function (optional): With RS-485 communication interface (partially compatible with MODBUS protocol), the DO value corresponding to the 4-20 mA current output can be set arbitrarily.

◇Notepad: can store 50 measurement data, users can record measurement data.

◇The function of hysteresis can be set arbitrarily to avoid frequent action of switch relay.

◇ Watchdog function: to ensure that the meter will not crash.

◇The core components are all from famous foreign brands.

◇ Factory settings can be restored. Power failure protection>10 years.
