Manufactur standard Single Stage Ro Controller - Online Dissolved Oxygen/Temperature controller (DO-6800) – JIRS

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.
