CB-25 Data Buoy Overview


The CB-25 Data Buoy is a simple, compact platform that integrates the X2-SDLMC Submersible Data Logger for both water and atmospheric observations. The buoy features (3) 1.5″ sensor pass-through ports, an integrated solar tower with (3) 4-watt solar panels, and a topside plate supporting a solar marine light, weather stations, and other environmental sensors. An optional EXO-S cage supports the YSI EXOs series of water quality sondes.
