fastCTD Profiler

The fastCTD Profiler offers a unique and versatile package designed to deliver the highest quality CTD casts at rapid drop rates.

An evolution of the miniCTD, it has a conductivity cell designed for optimum flow-through, a fast response thermistor temperature sensor and a 0.01% pressure sensor synchronously sampling at 32Hz deliver the highest quality profiles in a lightweight and robust package. The package is completed with an integral fluorometer based on Valeport’s new Hyperion range and optional Bluetooth communications module.

Sampling Modes

Continuous
Regular and synchronous data collection from all sensors up to 32Hz
Profile
Data is logged as the instrument descends (or rises), by a user defined pressure difference, through the water column
Rapid
Once the instrument is set to run mode no data is logged until a programmed trigger depth is reached (e.g. 2 meters below the surface). Completely programmable, the device can be set to record down casts data only, for example, when the probe stops descending and rises by a defined amount logging is stopped

Communications

The instrument is designed to operate autonomously. Setup and data extraction can be performed using a SubConn connector or via an optional Bluetooth connection with a PC. Multiple profiles can be recorded in the instrument by switching it on then off using the connector switch plug or magnetic switch key for Bluetooth operation. Bluetooth auto-pairing and discovery make connecting to the instrument simple and robust. The instrument can also operate in real time or cabled comms. Supplied with a traditional SubConn connector with a choice of communication protocols fitted as standard and selected by pin choice on the output connector:
