Valeport Ltd fastCTD Profiler

Description

An evolution of the miniCTD, the fastCTD Profiler has been designed to deliver the highest quality CTD casts at rapid drop rates. A conductivity cell designed for optimum flowthrough, a fast response thermistor temperature sensor and a 0.01% pressure sensor synchronously sampling at up to 32Hz deliver the highest quality profiles in a lightweight and robust package.
