Self cleaning dissolved oxygen sensor adopts the internationally leading fluorescence technology, which is based on the physics principle of quenching of active fluorescence by specific substances. The significant advantages of this fluorescence method of measuring dissolved oxygen are that it does not consume oxygen, has no flow limitation, does not require preheating of the electrolyte, and requires no maintenance and frequent calibration. It is also unaffected by hydrogen sulfide interference and offers excellent accuracy and stability.
