Abstract

A multi-functional sensor assembly includes an electrically non-conductive substrate defining at least a distal region, intermediary region, and proximal region that are each covered with electrically conductive traces. The proximal region is configured to be exposed to a media to be sensed and the distal and intermediary regions are configured to be protected from the media. The electrically conductive traces are connected to one or more electrodes to sense one or more of alkalinity, cyanuric acid concentration, or oxidant concentration of the media.
