1. An apparatus for determining spectral absorption by a specific substance in a fluid and indicating said spectral absorption to a remote display device, the apparatus comprising:

  • an energy source, said energy source emitting energy having one or more predetermined wavelengths, said energy being partly absorbed by said fluid in accordance with a known extinction coefficient corresponding to said one or more predetermined wavelengths;

    a sensing means for sensing energy emitted by said energy source, said sensing means producing an electrical output representing said spectral absorption;

    an interface means for supplying a predetermined reference voltage representing said one or more predetermined wavelengths and said extinction coefficient, said reference voltage cooperatively interacting with said remote display device;

    a support means for supporting said energy source, said sensing means and said interface means in proximity to said fluid; and

    connector means for communicating said electrical output and said reference voltage to said remote display device.
