Ozone concentration sensor

An apparatus and method provide measurement of a constituent of a fluid, such as ozone in ozonated water. The apparatus (100) includes a vessel (110) to contain the fluid, a light source (120, 120a, 120b) configured to direct a first band of light and a second band of light along a substantially sha...

Summary:An apparatus and method provide measurement of a constituent of a fluid, such as ozone in ozonated water. The apparatus (100) includes a vessel (110) to contain the fluid, a light source (120, 120a, 120b) 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 (130) 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.
