YSI Castaway CTD Hydrographic

YSI Castaway CTD Hydrographic is a hand deployable conductivity, temperature, and depth instrument for hydrologic profiling. An integrated LCD screen displays an intuitive user interface for deployment and immediate review of collected data including both statistics and profile plots.

The watertight, compact design features a tough rubber jacket for additional durability in harsh conditions. The system utilizes Bluetooth wireless communication, so no field cables or connectors are needed. Two AA batteries power the CTD for several days at a time and are easily replaceable without the use of any tools. This handheld device is an affordable, rugged, and portable instrument that simplifies any water profiling application.

Intuitive
With three taps of a magnetic stylus pen, simply drop the CastAway in the water, pull it up, and have conductivity, temperature, and depth measured in minutes. An attractive LCD screen provides easy access for setup, deployment, and immediate data review. Integrated GPS virtually eliminates the need for field notes. The beginning and end of every cast is logged to the internal recorder with position and time.

CTD Profiling and Analysis Software
Reviewing and analyzing CTD profiling data has never been easier. The included GIS software quickly downloads data from each of your CastAway CTDs automatically over Bluetooth to show the location of each cast on an interactive map. Customize your CTD data, GPS information, and plot comparisons all in one place. Analysis, plotting, editing, and exporting of data are quick and easy tasks.
