Product Options


The NexSens CB-50 Data Buoy is designed for quick deployment in emergency response situations including industrial spills and natural disasters. The buoy can be deployed from small boats, large vessels or even helicopters, making it the ideal choice for applications where water needs to be monitored at a moment’s notice.

Compatible instruments include turbidity sensors, dissolved oxygen sensors, hydrocarbon sensors, fluorometers, multi-parameter sondes, pressure transducers, and more.

The buoy is constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin and stainless steel frame. The 5.5” ID centre hole houses the X2-SDL data logging system, which includes integrated power supply and wireless antenna. A removable topside foam tower protects the electronics, supports solar marine lights, and offers a convenient lifting point via (3) 5/8” eyenuts. Optional accessories include instrument cages and mounting clamps to secure instruments to the platform.

Wireless telemetry options include cellular, Iridium satellite, and spread spectrum radio. Additional sensor inputs are available through the use of adapters. All sensor connections feature a double O-ring seal for a reliable waterproof connection.
