2D Horizontal Profiler - 300 m, 400 kHz

Up to 130 m horizontal profiling range; ideal for side-wall applications

The 2D Horizontal Profiler is the ideal tool for current measurements from a physical structure in, for example,
port entrances. This ADCP provides the two horizontal flow components at multiple distances from the mounting
and is commonly used in online applications where immediate access to current data is critical.
This instrument can also be used to perform river discharge measurements by River Insight.
