Abstract
A sensor for sensing turbidity of a liquid sample includes an illumination source, a scattered illumination detector, and a transparent, hydrophilic layer. The illumination source directs incident illumination into the liquid sample without passing through a gas. The scattered illumination detector is disposed to detect at least some illumination scattered in the sample. The transparent, hydrophilic layer is interposed between the source and the liquid sample, and interposed between the detector and the liquid sample. The transparent, hydrophilic layer inhibits bubble formation within the liquid sample proximate at least the incident illumination. A method for sensing turbidity is also disclosed.
