CTD Instruments & Environmental Sensors

CTD instruments are perhaps the most commonly used tool in an oceanographer’s armoury, providing detailed profile and time-series data on the measured parameters Conductivity, Temperature and Pressure, but more particularly the calculated values of Salinity, Density and Sound Velocity.

Valeport offers a selection of instruments, from simple plug on sensors for OEM applications through hand-held systems and devices for long term monitoring at fixed sites, to multiparameter profiling systems for deep ocean applications.

All Valeport CTDs use our own inductive Conductivity sensors. Digital sampling techniques ensure high accuracy, and the unique construction gives sensor stability at any depth. Temperature is always measured with a fast response PRT (Platinum Resistance Thermometer), and instruments also use industry standard strain gauge or resonant quartz pressure sensors.

Valeport have range of products for Environmental Monitoring applications. Integrated versions of these sensors into multi-parameter profilers are covered with SWiFTplus, fastCTD and rapidPro CTD.

SWiFTplus Turbidity

Valeport’s SWiFTplus Multi-Parameter Profiler with a Turbidity sensor combines survey-grade sound speed, temperature and pressure sensor technology with Turbidity observations.

SWiFTplus Chlorophyll a

Valeport's SWiFTplus Multi-Parameter Profiler with a Chlorophyll a sensor combines survey-grade sound speed, temperature and pressure sensor technology with Fluorometer observations.

SWiFT SVP

Designed for coastal, harbour and inland hydrographic survey use, the SWiFT SVP makes a seamless workflow a reality in a compact, robust and portable package.

MIDAS SVX2

Some users need the superior Sound Velocity data from an SVP with the Salinity and Density data from a CTD. So Valeport has come up with the unique MIDAS SVX2 that combines both technologies to give the best of both worlds.

fastCTDplus Chlorophyll a

An evolution of the miniCTD, the fastCTDplus multi-parameter profiler is designed to deliver the highest quality CTD and Chlorophyll a observations at fast drop rates.

fastCTD Profiler

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

Hyperion Chlorophyll a

Valeport’s Hyperion Chlorophyll a Fluorometer sensor delivers high-performance measurements of Chlorophyll a, in a compact & robust package ideal as a standalone sensor, for ROV and AUV integration or used as part of a multi-sensor array and data logger.

Hyperion Turbidity

Valeport’s Hyperion Turbidity sensor delivers high-performance measurements of turbidity, in a compact & robust package ideal as a standalone sensor, for ROV and AUV integration or used as part of a multi-sensor array and data logger.

MIDAS BathyPack

The BathyPack is one of Valeport's premier MIDAS products, using state of the art sensors to generate precision Sound Velocity and Density profiles for highly accurate depth and height data.
