RDO Optical Dissolved Oxygen System

SKU: RDO

Optical (luminescent-quenching) dissolved oxygen sensor — measures DO in wastewater aeration basins, ponds, and surface water without the membrane fouling, electrolyte depletion, or zero-drift issues of older membrane DO sensors. No daily zero calibration. Typical sensor life 1-2 years between cap replacements (vs 3-6 months for membrane). Best for municipal wastewater aeration optimization, fish farming, and any DO measurement where maintenance burden has historically been a problem. The Rosemount choice when 499ADO membrane sensor's lower cost is outweighed by maintenance time.
