Water-Right’s salt monitor (Model No. CV-3395) features a patented product design and the same easy “plug-and-play” installation as its Ozone Generator Kit. No additional transformers, relays or power supplies are needed. It is a standard function of the controller on select products. This feature works by taking a conductivity reading during the water softener’s brine cycle. The program then converts the reading into a percentage value of brine concentration. If the reading is low, an audible and visual alarm is triggered, notifying the homeowner that additional salt is required.
