CB-250 Data Buoy
Features
Versatile
The CB-250 is light enough to be deployed from most small boats, yet it offers adequate power and charging for rigorous instrument sampling and data transmission.
Self-Powered
Three integrated 15-watt solar panels are angled and evenly spaced around the buoy to capture sunlight from any direction and provide adequate battery charging.
Data Well
A 10-inch diameter by 19.5-inch tall data well provides a watertight housing for batteries, data loggers, sensors, and other hardware.
Connections
The data well lid provides pass-through connections for sensors, power, venting, and more. When integrated with the optional NexSens X2-CB data logger, the system is truly plug-and-play.
Pass-Through Ports
Three 2-inch pass-through ports allow for sensors to be mounted underwater while securely routing the cable. Instrument deployment pipes and custom sensor mounts attach to 4-inch NPT bottom threads.
Solar Beacon
The optional solar marine light has a one to three nautical mile range and securely mounts to the buoy top plate for maximum visibility.
Data Logging
The X2-CB data logger replaces the standard pass-through data well lid for turnkey systems. Alternatively, 3rd party data loggers can be integrated by the user inside the data well.
Wireless Communications
Communication options using the X2-CB data logger include Wi-Fi, radio-to-shore, cellular, and Iridium satellite.
Built to Last
Constructed of cross-linked polyethylene foam with a heavy polymer skin and an indestructible stainless steel frame, the CB-250 is designed for years of service.
