In-Situ® RDO® Technology How Does RDO Technology Work? Technical Training

RDO Optical Dissolved Oxygen Sensor • Method Name § • Luminescent dissolved oxygen method Sensor Components 1. The oxygen-permeable sensing element contains lumiphore molecules 2. Blue LED 3. Red LED 4. Photodiode Copyright © 2012 In-Situ Inc. This document is confidential and is the property of In-Situ Inc. Do not distribute without approval.

How Does Optical Measurement Work? 1. The optical RDO® Sensor initiates a reading by sequentially turning on the blue and red LEDs. 2. The blue light excites lumiphore molecules in the sensing element. 3. The red light provides a zero phase reference; it does not excite lumiphore molecules. Copyright © 2012 In-Situ Inc. This document is confidential and is the property of In-Situ Inc. Do not distribute without approval.

How Does Optical Measurement Work? 4. Excited lumiphore molecules emit red light. 5. The photodiode detects both red returned light from excited lumiphore molecules and reference light from the red LED. Copyright © 2012 In-Situ Inc. This document is confidential and is the property of In-Situ Inc. Do not distribute without approval.

How Does Optical Measurement Work? 8. 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. Copyright © 2012 In-Situ Inc. This document is confidential and is the property of In-Situ Inc. Do not distribute without approval.

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. Copyright © 2012 In-Situ Inc. This document is confidential and is the property of In-Situ Inc. Do not distribute without approval.

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.

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, p. H, or chloride. Copyright © 2012 In-Situ Inc. This document is confidential and is the property of In-Situ Inc. Do not distribute without approval.
