A CTD instrument is an oceanography sonde (French for probe) used to measure the electrical conductivity, temperature, and pressure of seawater. The pressure is closely related to depth. Conductivity is used to determine salinity. The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette. The sampling ...

Im tiefen Ozean kann solch eine CTD-Messung bis in 5000m Wassertiefe mehrere Stunden lang dauern. Die hydrografischen Daten sind auch heute noch essentiell für das Verständnis der Ozeanphänomene. Aus Temperatur- und Salzgehaltsfeldern lassen sich die Dichte- und Druckfelder im Ozean berechnen.

The model SD204 is also called CTD profiler, STD profiler, Sound Velocity profiler, CTD Instrument and CTD Sonde. The SD204 measures, calculates and records sea water conductivity, salinity, temperature, depth (pressure), sound velocity and water density.

The WiMo sonde can measure up to 20 water parameters as you can plug up to seven sensors at a time. The WiMo sonde benefits from its smart digital sensor suite including the wiper to maintain the sensors. You can connect, disconnect and calibrate the sensors whenever and wherever you need even with the functioning sonde on the field.

Une sonde Conductivity Temperature Depth (CTD) est une sonde mesurant la conductivité électrique, la température et la profondeur (Conductivity Temperature Depth) de l'eau. C'est un instrument utilisé en océanographie physique .

Our rugged CTD loggers feature durable, low-drift construction to deliver accurate data on conductivity, temperature and depth for a fraction of the cost of other equipment. Spot check or deploy continuously for flexibility with a single instrument.

A CTD is a series of small probes that can be deployed independently or incorporated into a variety of observing platforms such as remotely operated vehicles, gliders, or fixed observing buoys. On exploration vessels, a CTD is often attached to a larger metal water sampling array known as a rosette that is lowered into the water via a cable.

A CTD — an acronym for Conductivity, Temperature, and Depth — is the primary tool for determining essential physical properties of sea water. It gives scientists a precise and comprehensive charting of the distribution and variation of water temperature, salinity, and density that helps to understand how the oceans affect life.

The AML-6 is a multi-parameter sonde, designed to combine CTD data with other oceanographic parameters such as Dissolved Oxygen, pH, ORP, or Fluorometric sensors. This instrument has six sensor ports on the endcap; the sensor payload is modular and can be field-swapped to meet project requirements.

The model SD208 is often also called CTD profiler, STD profiler, Sound Velocity profiler, CTD Instrument and CTD sonde . The model SD208 measures, calculates and records sea water conductivity, salinity, temperature, depth (pressure), sound velocity and water density.
