Using the latest technology to measure dissolved oxygen, the next generation In-Situ® RDO® optical dissolved oxygen sensor offers several advantages for long-term and ambient water quality monitoring.
- Rugged design – Wiper-free sensor excels in demanding environments. Abrasion-resistant foil withstands fouling, high sediment loads, and rapid flow rates.
- Automatic setup – RDO sensor cap with pre-loaded calibration coefficients simplifies set up and eliminates programming errors.
- Fast response – Ideal for vertical profiling and dynamically changing conditions.

The rugged RDO sensor features:
High precision and accuracy
- Operates with very low drift for long periods of time
- Excels in hypoxic conditions
- Responds quickly and maintains stable response
Lower total cost of data acquisition and ownership
- Eliminates time-consuming maintenance – No flow requirements, stirring, fill solution, or frequent membrane replacement requirements.
- Reduces site visits – Calibration lasts for several months if sensor fouling is minimal and if the foil is not mechanically damaged or removed.
- Lowers scheduled maintenance costs – Field-replaceable caps streamline maintenance and eliminate programming errors.
Rugged performance
- Eliminates “poisoning” by sulfides and has no cross sensitivity to carbon dioxide, ammonia, pH, sulfide, sulfate, chloride, or hydrogen sulfide
- Withstands “thermal shocking” and photobleaching effects from ambient light
- Minimal hydration effects – No conditioning necessary prior to use
30-day no risk guarantee - If you don't like it after 30-days, just return for full credit.
