A DROP Salt Sensor is supplied with every Excalibur Smart Water Softener. Once connected to your DROP Hub, the salt sensor will notify you on the Dashboard page of the DROP application when more salt needs to be added to your brine tank. The height of the trigger point is specifically designed to give you plenty of notice to add more salt before you run out.
The Salt Sensor is available for purchase as a kit (with the DROP Hub) or as a stand-alone accessory if you already have the DROP Hub.
