RDO PRO-X Probe for Process Control & Aquaculture Applications

The In-Situ RDO PRO-X Probe uses breakthrough optical technology to measure DO in demanding process environments. The RDO PRO-X Probe offers several advantages.

Robust and Reliable
No calibration, conditioning, or membranes required
Stands up to harsh conditions—Inert construction will not corrode in saline samples.
Insensitive to common interferences such as hydrogen sulfide, chloride, ammonium, and oils
Sensor health diagnostics ensure peak performance

Cost Effective
Includes standard 10-m cable
Includes integral 4-20 mA, Modbus/RS485, and SDI-12 signal outputs
Eliminates the need for a separate, costly transmitter/controller

Accurate Results
±0.1 mg/L accuracy from 0 to 8 mg/L DO
±0.2 mg/L accuracy from 8 to 20 mg/L DO
±10% of reading from 20 to 50 mg/L DO
Fast response to DO and temperature changes
Consistent, reproducible results (< 0.05 mg/L reproducibility)
