In this dynamic demonstration, we showcase the Rosemount 499ADO-54 Dissolved Oxygen Sensor in action. You'll see how this membrane-covered amperometric sensor performs continuous dissolved oxygen measurements from 0 to 20 ppm in real wastewater treatment applications. Watch as we walk through its installation, calibration process, and compatibility with Rosemount transmitters like the 1056 and 1066-DO. Learn practical insights about its operating parameters, material construction, and optimal use in municipal and industrial aeration basins.
