SCHEDULE DEMO- Optimized for X3-SUB data logger with available 4G cellular or Iridium satellite telemetry
- Available with solar or blank top depending on battery type used in data logger
- Topside plate supports solar marine light, weather stations, and other sensors
The CB-75 Data Buoy is a compact, affordable, and easy to deploy platform for both water and atmospheric observations. At 21” (53.34cm) hull diameter and 40 lb. (18.14kg) weight, it’s ideally suited for tethered moorings. The buoy is designed to integrate the X3-SUB Submersible Data Logger, which includes external sensor ports to support weather stations, thermistor strings, multi-parameter sondes, Doppler current profilers, GPS, and other monitoring instruments.
Constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin, the CB-75 is designed for years of service. Select from a solar top with rechargeable battery pack for long-term deployments or a blank top with alkaline battery pack for short-term or seasonal applications. All electronics are housed in a quick-removable X3-SUB data logger package with wet-mateable connectors. A removeable instrument cage serves as counter-ballast and supports instrument mounting, while three 1.5” (3.81cm) pass-through holes facilitate cable routing of underwater sensors.
Available with integrated 4G LTE or Iridium satellite communications, the CB-75 Data Buoy sends data in real-time to the cloud-based WQData LIVE datacenter. In the Basic tier, this free service allows users to securely access and analyze data, as well as share data through an auto-report. Subscription-based tiers of WQData LIVE are also available for generating custom alarms, exporting data through an API or custom NDBC/GLOS formats, and providing a publicly-accessible version of the project website.
