Base•X CTD

Product Name:Base•X CTD
Description:Base•X is a rugged, shallow water logging instrument. Designed for profiling in coastal waters, the instrument includes a shackle, a sensor cage, and an LED status indicator to simplify deployment preparation. With AML’s new combined conductivity and temperature sensor, CT•Xchange, Base•X converts from a CTD to an SVP profiler with the switch of a single sensor head. Available in 100m and 500m versions, Base•X’s compact size and flexibility make it the ideal companion for the shallow water surveyor.
