ChemScan RDOX Optical Dissolved Oxygen Probe
CHEMSCAN RDOX PROBE
The ChemScan rugged dissolved oxygen (RDO) RDOX probe uses optical technology for measuring dissolved oxygen (DO) in demanding wastewater process environments, low-maintenance, easy to use and integrated design.

MUNICIPAL/INDUSTRIAL WATER AND WASTEWATER TREATMENT
The low-maintenance ChemScan RDOX Probe measures DO and provides extremely stable, accurate results. When the probe initiates a reading, a blue LED emits blue light, which excites lumiphore molecules in the sensing element. Excited lumiphore molecules emit red light, which is detected by a photodiode. Oxygen molecules quench the excited lumiphore molecules and prevent the emission of red light—a process called “dynamic luminescence quenching.” Determination of DO concentration by luminescence quenching has a linear response over a range of concentrations
Lumiphore molecules are excited by blue light and then emit red light, which is detected by a photodiode. Optical electronics report DO concentration in mg/L.
