Production Description:

RDO® PRO-X Optical Dissolved Oxygen Probe Description:
    The RDO PRO-X Dissolved Oxygen Probe uses optical technology (EPA-approved RDO technology for Clean Water Act programs) to measure dissolved oxygen and temperature in demanding process environments. This durable probe requires no calibration or conditioning prior to deployment and does not use membranes. The replaceable RDO Smart Sensor Cap stores calibration coefficients for automatic, error-free setup.
    Use flexible communication protocols (4-20 mA, Modbus/RS485, or SDI-12) and easily integrate with PLC systems, telemetry systems and/or HydroVu Data services for real-time feedback within your system.
    With the RDO PRO-X, NPDES permit holders can monitor influent, effluent and treatment processes and respond quickly to oxygen and temperature changes for more accurate and efficient process control.
 
RDO® PRO-X Optical Dissolved Oxygen Probe Applications:

•  MUNICIPAL/INDUSTRIAL WATER AND WASTEWATER TREATMENT
•  FOOD/BEVERAGE PROCESS CONTROL
•  AQUACULTURE SETTINGS
•  DAM DISCHARGE MONITORING
