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.
