ChemScan RDOX Optical Dissolved Oxygen Probe

Picture
 ​​
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.

​| RDO BROCHURE |
Picture
The RDOX Probe lets NPDES permit holder monitor influent, effluent and treatment processes, responding quickly to oxygen and temperature changes for more accurate result
ELIMINATE MAINTENANCE
  • ​Operates with very low drift for long periods of time
  • Responds quickly and accurately to oxygen and temperature changes across the full range.
  • Delivers consistent, reproducible results (<0.05 mg/L).
  • Eliminates membranes and filling solutions

SIMPLE DESIGN
  • Automates setup and reduces error-calibration coefficients are loaded into sensor cap.
  • Flexible communications-Standard 4-20 mA, Modbus/RS485, direct or using Control Point 2.0 with local display 
  • Direct connection eliminates the need for a transmitter or controller, and requires only 8 to 36 VDC power

COST EFFECTIVE
  • Runs aerators efficiently and mitigates risks.
  • Twist lock connection allows interchangeability with all ChemScan probes
  • Easily view and filter data using In-Situ telemetry systems and HydroVuTM Data Services.

ROBUST CONSTRUCTION
  • Resists abrasion and photobleaching effects.
  • Withstands high salinity environments-inert, non-corrosive materials used to construct probe body and sensor.
  • Insensitive to interferences that plague membrane-based sensors (hydrogen sulfide, chloride, ammonium, and others).

KEY ADVANTAGES
  • Long-lasting calibration—the probe maintains calibration and operates with no drift over long-term deployments, delivering consistent, reproducible results.
  • Automatic setup—the ChemScan RDOX Cap is pre-loaded with factory calibration coefficients, serial number, and manufacture date. ChemScan RDOX can use Classic, Fast, or ChemScan RDOX Cap. Ships with ChemScan RDOX Cap.
  • Sensor health diagnostics—internal indicators alert you about excessive wear and remind you about regular maintenance intervals.
  • Fast response—with patented signal processing, the probe responds quickly and maintains stability, even in dynamically changing conditions.
OFFERINGS
  • Simplified integration—use in conjunction with the ChemScan Control Point 2.0, SCADA/PLC Systems, or telemetry systems and HydroVu™ Data Services. the probe maintains calibration and operates with no drift over long-term deployments, delivering consistent, reproducible results.
  • Compliance certified—CE, FCC Class B heavy industrial immunityand emissions certifications. 
  • Twist-lock cable options—10m or custom lengths.

MUNICIPAL/INDUSTRIAL WATER AND WASTEWATER TREATMENT
​TECHNOLOGY
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
Picture
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.
