Abstract
An apparatus and method provide measurement of a constituent of a fluid, such as ozone in ozonated water. The apparatus includes a vessel to contain the fluid, a light source configured to direct a first band of light and a second band of light along a substantially shared path though the fluid, and a photosensor that senses the first band of light and the second band of light. The constituent has a greater absorption associated with the first band of light than with the second band of light. The method includes modification of a measured attribute of the component in response to the sensed second band of light to improve the accuracy of the measured attribute.

27. An apparatus for measuring an attribute of a constitute in a liquid, the apparatus comprising:
-
a vessel to contain the liquid; a light source that directs a first band of light associated with a first frequency and a first width and a second band of light associate with a second frequency and a second width along a substantially shared path through the liquid in the vessel, wherein the constituent has a great absorption associated with the first band of light than with the second band of light; and a photosensor that senses the first band of light and the second band of light passing along the substantially shared path. - View Dependent Claims (28)
