The SonTek Triton-ADV is a single-point, Doppler current meter designed specifically for low-power measurements in shallow water. The Triton-ADV Doppler processing techniques provide several important advantages: 3D velocity measurements in a remote sampling volume; invariant factory calibration (no periodic re-calibration required); simple operation; and excellent low-flow, shallow-water performance.

Robust velocity measurements in a compact, easy-to-use package

The Argonaut-ADV takes SonTek’s renown ADV technology and makes it practical and affordable for deployments in shallow streams, lakes, marshes or along the coast. Featuring an AutoVelocity range scaling, there is no need to pre-set the velocity range, its all done automatically by the instrument. A built-in recorder, SDI-12 interface, and battery enable you to either deploy
the Argonaut-ADV for autonomous operation, or connect it in real-time to a data logger. Its low velocity/shallow water capability make it the ultimate solution for marsh and wetland studies
