RDO Trio Self Cleaning Probe
RDO® Trio combines In-Situ's patented Rugged Dissolved Oxygen Technology with built-in conductivity and temperature sensors for reliable, real-time water quality monitoring. Integrated salinity compensation ensures accurate measurements across all environments, especially coastal and marine.
 
A copper guard and optional integrated wiper extend deployments. Unlike traditional electrochemical methods, RDO Trio requires no membranes, electrolyte, or water flow, and features a user-replaceable RDO Smart Sensor Cap for easy maintenance.
 
With Modbus/RS485 digital output, RDO Trio integrates seamlessly with PLCs and connects directly to the VuSitu mobile app and HydroVu data services for simplified setup, logging, and data access.
