LH-DO59 Online Dissolved Oxygen Sensor, 0-20 mg/L (CAT#: STEM-AL-4014-ZJF)

LH-DO59 Online Dissolved Oxygen Sensor is designed for continuous online measurement of dissolved oxygen. The sensing element converts the water-quality response into an electrical signal. Digital communication transfers measured values to a compatible controller or monitoring platform. The documented measurement range defines the intended analytical operating window. Integrated electronics support calibration data and configured operating parameters. The housing and sealing arrangement support immersion or flow-cell installation as specified. Temperature compensation or an integrated temperature element is used where documented. Low-power operation supports long-term monitoring installations. The sensor supports repeatable online measurement within the stated environmental limits.
