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…

Download our guide to read the basics of CTD, select the best CTD that fits your research needs between moored CTD and profiling CTD options, and learn more about water sampling technology.

CTD stands for conductivity, temperature, and depth. 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.

CTD stands for conductivity, temperature, and depth, and refers to a package of electronic devices used to detect how the conductivity and temperature of water changes relative to depth.

RBR’s inductive conductivity cell has taken its place at the forefront of high-accuracy CTD sensor technology as a proven standard that is robust, reliable, and uses a fraction of the power required for pumped CTDs.

Electrical conductivity temperature depth (CTD) sensors were used frequently and extensively. Long-term accurate CTD data is important for the study and utilization of oceans, e.g., for weather forecasting, ecological evolution, fishery, and shipping.

2025年3月10日 · D-2 Hybrid Conductivity Sensor. The Heart of the D-2 Incorporated CTD is its novel new ‘patented’ Hybrid conductivity sensor. This sensor has all the precision advantages of a 100% internal field cell coupled with a length that is ½ that of other competing sensors.

2025年2月3日 · A Conductivity, Temperature, Depth (CTD) Sensor, or CTD Profiler, collects data on water temperature, salinity, and pressure at different depths in the ocean.

Accurate and reliable Conductivity-Temperature-Depth (CTD) sensors in a compact, easy-to-integrate package for your AUV, ASV, ROV or underwater glider.

Valeport offers a selection of instruments including plug-in sensors for OEM applications, hand-held systems, devices for long term monitoring at fixed sites, and multiparameter profiling systems for deep ocean applications. All Valeport CTDs use …
