Measurement Principle
The dissolved oxygen sensor measurement is based on well-known oxygen fluorescence quenching technology. When oxygen sensing membrane film is excited by blue LED excitation light, the sensing film will emit red emission light. The phase delay between blue excitation and red emission is a function of oxygen concentration present. By measuring the phase delay the dissolved oxygen concentration can be calculated.
