Orion 087050MD RDO Dissolved Oxygen Sensor
Utilizes fluorescence technology to measure dissolved oxygen. Requires minimal maintenance, simplifying and streamlining the measurement process. The RDO electrode's speed, precision, and accuracy are comparable to or exceed those of current other dissolved oxygen measurement technologies.
Innovative optical dissolved oxygen measurement design
Accurate and reliable dissolved oxygen readings
Calibrate using water-saturated air, air-saturated water, zero point, or user-set points using the Wenker titration method.
Electrode cable lengths are available in 10m, 20m, 30m, 50m, with the longest option reaching up to 100m.
Industrial grade IP68, waterproof
