The YSI ODO RTU is an optical dissolved oxygen and temperature probe assembly that communicates directly with PLCs, data loggers, and SCADA systems via Modbus/RS-485 — no handheld meter or special software required. Simply wire the trimmed and tinned flying lead cable into your existing Modbus network for continuous, low-maintenance DO monitoring at fixed installations such as aquaculture tanks, ponds, wastewater treatment facilities, and process monitoring sites.
Note: Not compatible with ProSolo, ProODO, or any ProDIGITAL handheld meters. For handheld-compatible DO probes, see the YSI ODO/T Probe Assembly.
