Apure Fluorescence method KOG-206 Optical Dissolved Oxygen Sensor is based on the physics of specific substances on the activity of fluorescence quenching principle. The blue light from a light-emitting diode (LED) illuminates the fluorescent substance on the inner surface of the fluorescent cap. The fluorescent substance on the inner surface is excited to emit red light.
- High anti-jamming capacity
- Far transmission distance
Apure Fluorescence method KOG-206 Optical Dissolved Oxygen Sensor is based on the physics of specific substances on the activity of fluorescence quenching principle. The blue light from a light-emitting diode (LED) illuminates the fluorescent substance on the inner surface of the fluorescent cap. The fluorescent substance on the inner surface is excited to emit red light. By detecting the phase difference between the red and blue light, To calculate the concentration of oxygen molecules, through the temperature and pressure automatically compensate for the final output value.
- The sensor adopts new type of oxygen sensitive membrane,with NTC temperature compensated function,whose measurement result has good repeatability and stability.
- Won’t produce oxygen consumption when measuring and no requirement of flow rate and stirring.
- Breakthrough fluorescence technology,without membrane and the electrolyte and almost not need maintenance.
- Built-in self-diagnosis function to ensure the accuracy of data.
- Factory calibration,not need calibration for a year and can carry out field calibration. Digital sensor,high anti-jamming capacity and far transmission distance. Standard digital signal output,can achieve integration and networking with other equipment without controller.
- Plug-and-play sensor,quick and easy installation.
