Maretron BHW100 Bilge High Water Detector — Product description

This BHW100 Bilge High Water Detector is an available accessory for the SIM100. The sensor has a target molded into the plastic enclosure (opposite the side with the Maretron label). The target should be exposed so that when the water rises above the middle of the target, the BHW100 will indicate high water by illuminating the red LED and sending a signal to the Maretron Switch Indicator Module (SIM100). It should be mounted to a vertical wall in the bilge. The BHW100 acts immediately to rising water.
