1.  Introduction

An evolution of the miniCTD, the fastCTD Profiler has been designed to deliver the highest quality
CTD casts at fast drop rates as well as conventional casts.  A conductivity cell designed for
optimum flow-through, 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. 

Add in an integral Fluorometer based on Valeport's new Hyperion range, an optional Bluetooth
communications module and the fastCTD Profiler offers a unique and versatile solution.

If the equipment is used in a manner not specified by the manufacturer the protection provided by
the equipment may be impaired.

The safety of any system incorporating the equipment is the responsibility of the assembler of the
system.
