DO-6800

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
