Y502-A Online Optical Pen type Dissolved Oxygen Sensor
Y502-A Main Picture
Applications
Aquaculture, waste water plant, river, stream, and ocean monitoring
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.
Advantages of optical dissolved oxygen measurement
•Easy use, no membrane, no electrolyte.
•Long lifetime, maintenance free and less calibration.
•No flow dependency and fast response.
•Immune to electrical interference, no chemical interference.
