KFDO310 integrated on-line fluorescence dissolved oxygen sensor is designed and made based on the quenching principle of excited fluorescence of specific substances in physics. The blue light from the light-emitting diode illuminates the fluorescent material on the inner surface of the fluorescent cap. 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 molecule can be calculated, and the final value can be output by temperature automatic compensation.
No electrolytes, no polarization
No need to consume oxygen, not affected by the flow rate
Built-in temperature sensor, automatic temperature compensation
Free from chemicals like sulfides
Small drift, fast response, more accurate measurement
Maintenance-free, long service life, lower use cost
Fluorescent caps are easy to replace
RS-485 interface, Modbus-RTU protocol
