RDO Titan Process Probe


The RDO Titan Process Probe is EPA-approved for Clean Water Act programs, using optical technology to measure dissolved oxygen and temperature in demanding process environments.

Ideal for long-term monitoring and process control, the instrument’s titanium body features a robust optical sensor that requires no membranes, with minimal maintenance and calibrations.



  • Titanium construction

  • Includes detachable cable available in custom lengths (Modbus only)

  • 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



  • Performs in harsh environments – Titanium construction resists corrosion, outlasting other specially coated instruments.

  • Minimal maintenance – Sensor cap stores calibration coefficients, serial number and expiration date. Simply pop on a new cap when the old one expires.

  • Accurate, reliable data – Unlike membrane-based sensors, probe is insensitive to common interferences, with automated calibration to prevent long-term drift.
