USABlueBook's RDO PRO-X (Rugged Dissolved Oxygen) DO sensor uses the latest optical technology for measuring oxygen in your process. Corrosion-resistant sensor is inert to common interferences found in water and wastewater plants, such as hydrogen sulfide, chloride, chlorine and ammonium. Maintenance is easy! There are no fragile membranes or electrolyte solutions to replace—simply replace the sensor cap every two years, and you're back in business.

This flexible standalone sensor reduces equipment costs because you don't need to purchase a separate controller. It features low-voltage power requirements and a 3-wire 4-20 mA transmitter output signal that interfaces with many common external devices like PLCs, variable frequency drives and chart recorders. If you want a local display readout, just use any generic panel meter. Sensor features CE and FCC Class A heavy industrial immunity and emissions certifications, which means it won't interfere with other nearby devices—and those other devices won't interfere with it, either.

Includes: sensor cap, calibration/storage sleeve and manual. 3-year sensor warranty; 2-year cap warranty (1 year from date of installation).

Note: Order the RDO PRO communications device kit separately (stock # 43029) to link the RDO PRO-X sensor to your PC via a USB port for initial setup and calibrations, view live measurement values and access sensor accuracy parameters.
