1. A combination pH and ammonia measuring device for simultaneous, continuous measurement of solution pH and ammonia, the combination comprising:

  • a submersible member, or a plurality of spatially proximate, coordinately-submersible members, suitable to be at least partially submersible in a solution;

    at least one submersible ammonia-sensing portion integral with or attached to the submersible member or to one or more of the proximate submersible members, the at least one ammonia-sensing portion having at least one stable detection means suitable to provide for a continuous visual indicator of solution ammonia concentration;

    at least one submersible pH-sensing portion integral with or attached to the submersible member or to one or more of the proximate submersible members, the at least one pH-sensing portion having at least one stable detection means suitable to provide for a continuous visual indicator of solution pH;

    a visual ammonia indicator comparison component, comparable with the at least one continuous visual indicator of the at least one ammonia-sensing portion to provide for standardized quantitative determination of solution ammonia concentration; and

    a visual pH indicator comparison component, comparable with the at least one continuous visual indicator of the at least one pH-sensing portion for standardized quantitative determination of solution pH, wherein the combination is suitable to provide for simultaneous, continuous measurement of solution pH and ammonia.
