Signature250
Intermediate current profiling range that includes wave height/direction and ice tracking capability
The Signature250 ADCP is a medium-range current profiler with a suite of extra features. It has a current profiling range of 200m and can measure wave height, period and direction at depths as great as 150m. The Signature250 ADCP can also measure ice thickness, as well as the speed and direction of drifting ice. Its compact design and low power consumption make it an ideal tool for long-term deployments in all waters.
