The Submerged Installation Of The Dissolved Oxygen Sensor For Aquaculture Has An RS485 Output DO Probe
1. Product Introduction
The KNF-103B series fluorescence dissolved oxygen sensor adopts the new generation of fluorescence lifetime technology and independently develops high-performance fluorescence materials. It does not consume oxygen, has no flow rate limit, requires no electrolyte, needs no maintenance or calibration, is not disturbed by hydrogen sulfide, and has excellent stability. Built-in temperature sensor with automatic temperature compensation. RS485 output enables networking without a controller.

2.Features of KNF-103B Fluorescence Dissolved Oxygen Sensor
1. Digital sensor, RS485 output, supporting MODBUS
2. No membrane, no need for electrolyte, no interference, and no need for frequent calibration
3. It does not consume oxygen and has no flow rate limit
4. Built-in temperature sensor with automatic temperature compensation
3. Measurement principle of KNF-103B fluorescence dissolved Oxygen sensor:
The fluorescence dissolved oxygen sensor is based on the principle of quenching active fluorescence by specific substances in physics. Blue light emitted by a light-emitting diode (LED) shines on 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 and blue light and comparing it with the internal calibration value, the concentration of oxygen molecules is calculated. The final value is automatically compensated for by temperature and pressure.
