  • Optical nitrate sensor for multiparameter water quality measurement
    Patent number: 11073475
    Abstract: An optical nitrate sensor features a signal processor or signal processing module configured to: receive signaling containing information about a measurement (M) of UV optical absorbance of nitrate dissolved in water of a UV light that is generated by a UV LED centered at 229 nm and that traverses a confined volume of the water within a prescribed region of a sensor body, and also about a reference sample (R) of a portion of the UV light not traversing the confined volume of the water; and determine corresponding signaling containing information about the concentration of nitrate dissolved in the water, based upon the signaling received.
    Type: Grant
