Base•X₂ CTD

Product Name:Base•X₂ CTD
Description:The latest generation of AML Oceanographic’s Base•X presents the best profiler technology of today in a compact form. Available in 100m and 500m versions, Base•X₂ retains the size of its predecessor while gaining WiFi connectivity and GPS . Data is automatically downloaded and processed into desired manufacturer formats, saving valuable time for the operator. With AML’s new combined conductivity and temperature sensor, CT•Xchange, Base•X₂ converts from an SVP to a CTD profiler with the switch of a single sensor head.
