This is the same 15' sensor that comes with the Aquagate C100 to provide additional leak detection. Note: Only the 15 sensor plugs into the Aquagate C100. You can connect up to 4 15' sensors to a single Aquagate. All the other sensors plug into the 15' sensor or each other. You can plug as many 3', 8' and 25' sensors to other 15', 3', 8' or 25' sensors that you like, however Aquagate recommends a max of 4 sensors per channel. Works with Aquagate C100, which has been discontinued. Limited to stock on hand.
