    dissolved oxygen, for water quality

  • Technology:


  • Field:


  • Other characteristics:



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)
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.
