WebDissolved Oxygen. Low DO levels usually indicate serious pollution. Adequate amounts are crucial for fish life, but conversely, DO must be excluded from boiler feedwater to prevent … WebOptical DO sensors measure the DO concentration of liquid media or air based on the quenching of luminescence in the presence of oxygen. Since oxygen affects both the intensity and the lifetime of the luminescence, either may be used to measure DO. There are three methods of measuring optical dissolved oxygen:
