YSI ODO RTU Probe Assembly (DO + Temperature, Modbus/RS-485)

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. Optical luminescence DO — no stirring required, no membrane to replace frequently Modbus/RS-485 (4-wire), 9600 baud default (user programmable) Power: 10–16V DC, 15 mA max 2-year warranty on cable, probe, and ODO sensor cap; user-replaceable DO cap Trimmed and tinned flying lead cable — wires directly into existing Modbus network SPECS MANUAL
