Product Specification

RDO® Blue Optical Dissolved Oxygen Sensor Description:

    RDO Blue uses In-Situs patented Optical Rugged Dissolved Oxygen technology, an EPA-approved dissolved oxygen measurement method ideal for measuring DO and temperature in even the harshest environments. Suitable for handheld use or long-term deployment in fresh water or saltwater, this low-maintenance dissolved oxygen probe offers robust performance at a lower cost than other DO meters.

    RDO Blue requires no calibration or conditioning prior to deployment and doesnt use membranes. The replaceable RDO Smart Sensor Cap stores calibration coefficients for automatic, error-free setup. And a unique, three-layer system provides unmatched chemical and abrasion resistance.

    Use included Modbus/RS485 communication protocol to easily integrate with PLC systems or telemetry with HydroVu data services for real-time feedback and process control.
