Measure dissolved oxygen levels without the difficulties of membrane replacement by using the Orion™ RDO™ Dissolved Oxygen Probe.

• Utilizes the latest lumiphore technology for measuring DO
• Once-a-year maintenance with a simple cap replacement
• Sensor cable lengths of 3, 6, 10, 15, or 30 m (10, 20, 30, 50, or 100')
• IP68-rated, waterproof

The Orion™ RDO™ dissolved oxygen probe offers a dissolved oxygen concentration range of 0.00 to 20.0mg/l, and a dissolved oxygen saturation range of 0.0 to 200%. Each probe order includes RDO probe, optical cap, stainless steel sensor guard, and calibration sleeve.

RDO (Rugged Dissolved Oxygen) Probe uses optical DO technology for problem-free measurement.
