Sontek CastAway-CTD With Dimensions Height 20.32 cm is a small, rugged, and technically advanced CTD designed for profilingto depths of up to 100m. The system incorporates modern technical features which allow itto achieve a 5 Hz response time, fine spatial resolution, and high accuracy. It uses a sixelectrode flow-through conductivity cell with zero external fields and a rapid responsethermistor to attain high measurement accuracy. The instrument is simple to deploy, doesnot require a pump, and is hydrodynamically designed to free a fall rate of 1 m/s.The integrated real-time data display screen, internal GPS sensor, and automated wirelessdata transfer are unique features that simplify data collection.
