• Built-in temperature sensor, automatic temperature compensation
• Chemical interference from sulfide
• In drift, fast response, more accurate measurements
• Maintenance-free longer applicable period, lower cost
• Fluorescent cap replacement is simple
• Supports RS-485, MODBUS protocol

RDO-200 Dissolved Oxygen Sensor Measuring principle:
luminescent dissolved oxygen sensor is based on a specific matter physics quench the fluorescence of the active principle. From a light-emitting diode Blue light (LED) in the fluorescence emitted by the phosphor surface of the cap, the inner surface of the fluorescent substance is excited, emit red light, by detecting the phase difference between the red and blue, and with internal calibration values and compared to calculate the concentration of molecular oxygen, temperature and pressure through the automatic compensation output a final value.
