CTD and Multiparameter Instruments

The CTD is perhaps the most commonly used tool in an oceanographer's arsenal. It provides 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.

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

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