Product Description

Online Dissolved Oxygen/Temperature controller
Code: DO-6800 

Description:

1. DO-6800 online Dissolved Oxygen Temperature Transmitting Controller is a micro computerized precision instrument.   
2. The large LCD display, English menu operation.
3. 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
4. Screen displays alarm status and accompanied by a switch ON / OFF signal output
5. Automatic Temperature Compensation: Automatic 0ºC to 60ºC
6. 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.
7. Notepad: can store 50 measurements, the user can record measurement data.
8. Hysteresis amount can be set freely to avoid frequent switching relay action
9. Watchdog function: to ensure that the instrument will not crash  
10. Core devices from famous foreign brands
11. 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.
