The 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 antifouling guard and optional integrated wiper extend deployments. Unlike traditional electrochemical methods, the 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, it integrates seamlessly with PLCs and connects directly to the VuSitu mobile app and HydroVu data services for simplified setup, logging, and data access.Why it works Integrated cleaning. Flat-face design, integrated wiper, and antifouling guard reduce buildup in high-fouling environments. Automatic fouling recovery. With the optional wiper, the probe self-clears false low DO events based on user-set thresholds. Integrated salinity compensation. Maintains accurate DO readings in environments with fluctuating salinity. EPA-approved method. RDO luminescence-quenching sensors do not consume oxygen and do not require water movement. Smart Sensor Cap. 90-point factory calibration stored in the replaceable cap. Open Modbus API. Seamless integration with SCADA systems, controllers, and telemetry devices. Base configuration; options are configured at order time. Contact us to spec the right configuration.
