CTD Systems

A Conductivity Temperature and Pressure (CTD) system is an instrument composed of several sensors used mainly in oceanography. The conductivity is measured to calculate the salinity of the water. By combining salinity with temperature it is possible to calculate the density of water. CTD systems can be equipped with a rosette (metal frame) which holds multiple bottles for taking samples at different depths.
