Argonaut®-XR

near shore deployments
close
info:

The Argonaut-XR offers exceptional value for near shore deployments in less than 40 m of water. Designed specifically for mounting on the bottom of a river, channel, or harbor, the XR features a special mode that automatically adjusts one of its measurement cells for changing water level. Its small size, rugged build, and flexible system architecture make the XR attractive for both real-time operation and autonomous deployments.

FlowTracker2® Handheld-ADV®

Wading Discharge Measurement
close
info:

FlowTracker2 with optional pressure sensor for depth data Now with optional pressure sensor feature! The new FlowTracker2 (FT2) handheld Acoustic Doppler Velocimeter (ADV®) has all the technology you have grown to know and trust with the original FlowTracker, but now comes with functional, modernized features   (Bluetooth, GPS and large color screen, to name only a few) based on the evaluation and feedback from hydrologists, researchers and scientists who have made the FlowTracker their instrument of choice.

 But the real power becomes clear from the moment you start to collect data. Each step of the way FT2 guides you along the measurement process with visual prompts and SmartQC audio alerts just in case something important needs your attention.

 FT2 handheld software is intuitive, easy to navigate and includes real-time plots of point data, QC parameters, and measurement verticals, giving you everything you need at-a-glance.  Get defensible data correctly, the first time, every time, and minimize data handling back at the office.

With rugged construction for any climate and multiple display options for both day and night, FT2 goes whenever and wherever you need it to go.
