RS485 Fluorescence Dissolved Oxygen Sensors

DFRobot RS485 Fluorescence Dissolved Oxygen Sensor provides a high-stability solution for measuring dissolved oxygen in both freshwater and high‑salinity marine environments. These sensors operate on the principle of fluorescence quenching, an optical method that measures the phase shift of light caused by oxygen molecules. The RS485 sensors deliver a high-accuracy measurement range of 0mg/L to 20mg/L (0% to 200% saturation) with an error of just ±3% FS. These sensors include a maintenance-free optical design, built-in automatic temperature compensation, and simple system integration via the standard ModBus-RTU protocol. The RS485 fluorescence dissolved oxygen sensors feature an IP68 waterproof rating and are ideal for freshwater aquaculture, wastewater treatment, and long-term environmental monitoring.
