The YSI ODO RTU with Conductivity is an optical dissolved oxygen, conductivity, salinity, and temperature probe assembly that communicates directly with PLCs, data loggers, and SCADA systems via Modbus/RS-485. The built-in four-electrode conductivity cell automatically compensates for salinity in DO calculations — eliminating manual correction and improving accuracy in brackish or variable-salinity environments.
Note: Not compatible with ProSolo, ProODO, or any ProDIGITAL handheld meters. For handheld-compatible DO/CT probes, see the YSI ODO/CT Probe Assembly.
