Prevent Pressure Build-Up in CB-Series Data Wells
Due to temperature and barometric pressure changes, or in some cases, battery off-gassing, buoys with sealed compartments, including battery and data wells, can build up pressure or establish a vacuum over time. To reduce these effects, NexSens CB-Series buoy lids are equipped with either a membrane vent or, for rough water applications, a 5 PSI […]
