RDO-206A integrated on-line fluorescence dissolved oxygen sensor is designed and fabricated based on the quenching principle of excited fluorescence by specific substances in physics. The blue light emitted by the light emitting diode (LED) irradiates on the fluorescent substance on the inner surface of the fluorescent cap, and the fluorescent material on the inner surface is excited and emits red light. by detecting the phase difference between the red light and the blue light and comparing it with the internal calibration value, the concentration of oxygen molecules is calculated, and the final value is automatically compensated by temperature.
• No electrolyte is required and will not be polarized.
• No oxygen consumption, not affected by flow rate.
• Built-in temperature sensor, automatic temperature compensation.
• Free from interference by chemicals such as sulfides
• Small drift, rapid reaction, more accurate measurement.
• Maintenance-free, long service cycle, lower cost of use.
• Simple replacement of fluorescent cap.
