Description:
● DO-6800 online Dissolved Oxygen Temperature Transmitting Controller is a micro computerized precision instrument. ● The large LCD display, English menu operation. ● 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 ● Screen displays alarm status and accompanied by a switch ON / OFF signal output ● Automatic Temperature Compensation: Automatic 0℃ to 60℃ ● 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. ● Notepad: can store 50 measurements, the user can record measurement data. ● Hysteresis amount can be set freely to avoid frequent switching relay action ● Watchdog function: to ensure that the instrument will not crash ● Core devices from famous foreign brands ● Restore the factory settings. Power-down protection> 10 years Application: Widely used in the detection and control of dissolved oxygen in various water treatments, boiler water deoxygenization, environmental monitoring, aquaculture and other fields.
