More info

The In-Situ RDO PRO-X Optical Dissolved Oxygen Sensor is an extremely stable, accurate, low-maintenance optical dissolved oxygen sensor for long-term environmental monitoring. The RDO PRO-X sensor measures dissolved oxygen using the latest dynamic luminescence quenching technology that offers many advantages over Clark-type DO sensors, including stir-independence and insensitivity to interferences such as hydrogen sulfide, chloride, and ammonium. A user-replaceable sensor cap with pre-loaded calibration coefficients is replaced annually, eliminating the need for bi-monthly membrane replacements.
The In-Situ RDO PRO-X Optical Dissolved Oxygen Sensor sensor includes a 10m cable terminating in bare wires for connection to data loggers and PLC's. The sensor is constructed with inert material and pressure-rated to 500 PSI, making it an ideal solution for highly saline or deep water environments. Common applications include dam discharge monitoring, multi-point dissolved oxygen profiling, and municipal process monitoring.

Features:

  • Flexible communication protocols (4-20 mA, Modbus/RS485, SDI-12)
  • Available in standard 10m cable or twist-lock in custom lengths
  • EPA-approved
  • Most accurate DO probe on the market (up to ±0.1 mg/L)
  • Doesn’t corrode in saline environments
  • No interference from hydrogen sulfide, chloride, ammonium, or oils
  • Automated sensor cap diagnostic alerts
  • Requires only 8 to 36 VDC

Benefits:

  • Simplify setup and monitoring – Flexible communication protocols connect to your existing controllers, SCADA, or PLCs.
  • Accurate, reliable data – Resists abrasion and photobleaching, with automated calibration that prevents long-term drift.
  • Easy maintenance – Smart sensor cap stores vital information and alerts you when it’s time to replace.
  • 24/7 data access – View and filter data easily using telemetry systems and HydroVu Data Services
