What are the types of dissolved oxygen sensors used for measuring oxygen in water?
Dissolved oxygen (DO) in water is measured using several types of sensors, each based on a different principle. The main types are: 1. Optical (Luminescent / Fluorescence Quenching) DO Sensors Based on the principle that dissolved oxygen quenches (reduces) the fluorescence of a dye. A blue or UV LED excites a luminescent dye; the presence […]
