Abstract

Chemical indicator apparatuses containing one or more chemical indicators for use in monitoring the quality of water in an aquatic environment. The apparatuses are designed and configured to be submersible in the water that is being monitored. In some embodiments, each apparatus includes a plurality of immobilized-dye-based chemical indicators that undergo a physical change as levels of one or more constituents of the water change. Such indicators can be read by one or more suitable optical readers. These and other embodiments are designed and configured to be movable by a corresponding monitoring/measuring apparatus, for example, via a magnetically coupled drive. Also disclosed are a variety of features that can be used to provide a chemical indicator apparatus with additional functionalities.
