RS485 Digital DO Sensor For Water Treatment Monitoring And Dosing Control
The OPD79 fluorescence dissolved oxygen sensor adopts a new generation of fluorescence lifetime technology, and our company independently develops high-performance fluorescent materials.
No oxygen consumption, no flow rate limitation, no electrolyte, no maintenance and calibration, no hydrogen sulfide interference, and excellent stability. Built-in temperature sensor, automatic temperature compensation. RS485 output, can be networked without a controller.
The OPD79's fluorescence on-line dissolved oxygen analyzer uses the most advanced and best optical sensor in the world today. It is an extremely wear-resistant and extremely stable optical light-emitting device, which greatly reduces maintenance costs, extends service life, and has fully automatic self-cleaning and self-validation functions.

Brief introduction:
● Fluorescence principle
● The digital sensor is conducive to long-distance signal transmission without serious
signal attenuation
● No calibration required, can meet the requirements of field work, short-term or
long-term operations
● Without consuming oxygen, accurate measurement can be achieved when oxygen
concentration is low
● All-in-one package, can be used with the online transmitters, DTU, and portable
instruments
● RS485 interface, Modbus RTU, support access to standard industrial control system
● The protection grade is IP68, can work continuously and stably under water for a long
time
● Internal storage of calibration data, support offline calibration, plug and play on site
Aplication:
◇ Sewage
◇ Surface water monitoring
◇ Aquaculture water bodies
◇ Urban sewage treatment
◇ Industrial wastewater treatment
◇ Aquarium
FAQ
4. How long has the fluorescence technology been in use?
Fluorescence technology used to detect oxygen uptake in the medical industry for decades.
In the early 2000s, the technology was adapted for use in measuring dissolved oxygen in biological reactors.
The key issues in making the technology viable in the water treatment industry were the durability of the sensing element and cost.
Another important concern was packaging the system in a way that was easy to use and required very little maintenance.
5. What is the wire length of the DO electrode?
A: The lead wire of this electrode is 1 m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.
