Part Number: Titan

The RDO Titan Aquaculture Probe continuously measures dissolved oxygen and temperature in ponds, raceways, tanks, and other demanding environments. Advanced optical technology plus a titanium body makes it the most accurate high-durability DO probe on the market today.

Ideal for long-term aquaculture management, the robust optical sensor requires no membranes, and only minimal maintenance and calibrations.


  • Titanium construction
  • 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
  • Hydrogen sulfide, chloride, ammonium, and oils don’t
  • Automated sensor cap diagnostic alerts


  • Performs in harsh environments – Titanium construction resists corrosion, outlasting other specially coated instruments.
  • Improve yields – High-accuracy DO probe lets you optimize pond conditions for maximum growth.
  • Minimal maintenance – Auto-calibration prevents drift, and sensor cap stores calibration coefficients, serial number and expiration date. Simply pop on a new cap when the old one expires.
