1. Apparatus for simultaneously determining the relative concentration of two solutions each of unknown concentration comprising:

  • a single source of light;

    a source of reference voltage;

    first conversion means responsive to the source of reference voltage and to the amount of light from said light source transmitted through one of said two solutions of unknown concentration for repeatedly determining the concentration of said one solution;

    second conversion means responsive to said source of reference voltage and to the amount of light from said light source transmitted through the other of said two solutions of unknown concentration for repeatedly determining the concentration of said other solution; and

    arithmetic means simultaneously receiving inputs from each of said first and second conversion means for repeatedly determining the relative concentration of said two solutions.
