$0.00

The online dissolved oxygen meter is an online intelligent dissolved oxygen detector produced by our company with foreign technology. It adopts imported components and dissolved oxygen film heads, based on the latest polarographic analysis technology, advanced production technology and surface mount technology. This series of advanced analytical techniques is used to ensure the long-term stability and reliability of the instrument. It has Chinese menu operation, notebook storage measurement data, 485 communication and other functions. Can be widely used in chemical fertilizer,metallurgy, environmental water treatment engineering, pharmaceutical, biochemical, food, aquaculture and tap water and other solutions in the continuous monitoring of dissolved oxygen values.

We will be in contact with you within two business days.

Feature:

1. The large LCD display, English menu operation.
2.Multi-parameter display at the same time: the value of dissolved oxygen,temperature, output current, alarm points, etc. Intuitive and easy to read, and alarm for range over run.
3.Screen displays alarm status and accompanied by a switch ON / OFF signal output
4.Automatic Temperature Compensation: Automatic 0℃ to 60℃
5.Communication function (optional): RS-485 communication interface(MODBUS protocol is partially compatible), 4 to 20 mA current output corresponding to the DO value can be set freely.
6.Notepad: can store 50 measurements, the user can record measurement data.
7.Hysteresis amount can be set freely to avoid frequent switching relay action
8.Watchdog function: to ensure that the instrument will not crash
9.Core devices from famous foreign brands
10.Restore the factory settings. Power-down protection> 10 years
