1. A sensor, comprising:

  • a sensor head having a 90 degree cutout defining a first planar surface intersecting at 90 degrees to a bottom surface of the sensor head and defining a second planar surface parallel to the bottom surface and intersecting at 90 degrees to a lateral surface of the sensor head, the sensor head comprising;

    a light source chamber including an ultraviolet (UV) light source that emits a first UV wavelength;

    a light source window positioned in the first planar surface that transmits the first UV wavelength into an analytical area containing a sample having an unknown concentration of a chemical that exhibits fluorescent characteristics;

    a detector window positioned in the second planar surface; and

    a detector chamber including a UV detector that detects fluorescence emissions of the sample at a second UV wavelength transmitted through the detector window; and

    a controller that calculates the concentration of the chemical in the sample based on the detected fluorescence emission.
