DO is an important water quality parameter that effects marine life, the taste of drinking water, and the corrosiveness of a water sample.
WebThis method uses the quenching phenomenon of oxygen to calculate the level of DO. Fluorescence from a fluorescent material excited by light from a blue light-emitting diode (LED) is quenched by oxygen passed through a DO permeable layer. The higher the DO level is, the stronger the quenching phenomenon is and the less fluorescence the detector ...
