Technical Training

3. RDO Optical Dissolved Oxygen Sensor
Method Name
Luminescent dissolved oxygen method
Sensor Components
The oxygen-permeable sensing element contains lumiphore molecules
Blue LED
Red LED
Photodiode

4. How Does Optical Measurement Work?
The optical RDO® Sensor initiates a reading by sequentially turning on the blue and red LEDs.
The blue light excites lumiphore molecules in the sensing element.
The red light provides a zero phase reference; it does not excite lumiphore molecules.

5. How Does Optical Measurement Work?
Excited lumiphore molecules emit red light.
The photodiode detects both red returned light from excited lumiphore molecules and red reference light from the red LED.

6. How Does Optical Measurement Work?
Sensor electronics compute DO concentration as a function of phase and temperature.
Sensor electronics automatically compensate DO values for temperature. DO values can be compensated for salinity and barometric pressure.

7. Summary of RDO Optical Technology

8. Advantages of Optical RDO Technology
Accurate results—Sensor operates with no drift over long-term deployments. Unlike membrane-based sensors, the RDO Sensor excels in hypoxic conditions. No sample flow or stirring is required.
Minimal maintenance—No hydration, conditioning, or special storage is required. No membranes or electrolyte/filling solution to replace. RDO Cap requires annual replacement—simply pull off the cap and snap on a new one.
Long-lasting calibration—The RDO Sensor can be deployed for several months if sample fouling is minimal and if the lumiphore is not damaged. Membrane-based sensors typically require calibration every 2 weeks, depending on sample conditions.

9. Advantages of Optical RDO Technology
Rugged performance—Wiper-free design excels in demanding environments. Abrasion-resistant lumiphore withstands fouling, high sediment loads, and rapid flow rates. The lumiphore is not affected by photobleaching and stray light.
Automatic setup—RDO Cap is pre-loaded with factory calibration coefficients, serial number, expiration clock, and manufacture date for traceability. Programming errors are eliminated.
Fast response—The RDO Sensor responds quickly and maintains a stable response. Ideal for dynamically changing conditions and vertical profiling.

10. Advantages of Optical RDO Technology
EPA approved—On May 18, 2012, the U.S. Environmental Protection Agency granted nationwide approval to 3 RDO methods. These methods can be used to determine Biochemical Oxygen Demand (BOD), Carbonaceous Biochemical Oxygen Demand (CBOD), and Dissolved Oxygen (DO) under the Clean Water Act.
Patented signal processing—Proprietary design allows for stable, fast response and has low power requirements.
Minimal interferences—Unlike membrane-based sensors, the RDO Probe is unaffected by sulfides, sulfates, hydrogen sulfide, carbon dioxide, ammonia, pH, or chloride.

11. Conductivity Theory
Uses In-Situ conductivity cell design for optimum range and accuracy
Balanced 4-electrode conductivity cell with all titanium electrodes
4 outer electrodes are drive electrodes—these are the powered electrodes
Alternating voltage applied to reduce polarization
Inner sense electrodes are used as a feedback loop to determine the conductivity range of the solution
Cell in horizontal placement to facilitate bubble shedding
Center wall used to create linearity and accuracy
Forces the current around the wall and makes the cell K larger, thus creating better range and sensitivity
Full dynamic range from 5 to 100,000 µS/cm
