Aurora's DOP1-series Process Optical Dissolved Oxygen Probe utilizes fluorescence quenching technology.
With this technology, the quenching of fluorophores by oxygen molecules dissolved in the water decreases the fulorescence intensity and lifetime, which is detected by the photodetector and allows the dissolved oxygen concentration to by quantified accurately and in a consistent manner.

Unlike traditional electrochemical technologies (e.g. polarographic and galvanic) used for the meausrement of dissolved oxygen, optical technology does not consume oxygen during measurement. Also the optical technology does not require filling solutions , a warm up period, nor sample flow. 

The measured dissolved oxygen concentration is automatically compensated by the integration data from temperature and pressure sensors and sophisticated algorithms in the firmware.
