American Orion 087020MD RDO Dissolved Oxygen Electrode
Utilizes fluorescence technology to measure dissolved oxygen. Requires minimal maintenance, simplifying and streamlining the measurement process. The speed, precision, and accuracy of the RDO electrode 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
Calibration using water-saturated air, air-saturated water, zero point, or using the Winkler titration method to set user points
Electrode cable lengths are available in 10m, 20m, 30m, 50m, with the longest option extending to 100m.
Industrial grade IP68, waterproof
