Apply For Services

ISO 22804:2023 is a standard that provides technical requirements for marine Conductivity-Temperature-Depth (CTD) profilers. It ensures consistent reporting on test methods, inspection rules, marking, packaging, transportation, and storage of these instruments used in marine fixed-point and mobile observation platforms. The standard applies to various types of shipborne CTD measuring instruments that directly measure conductivity, temperature, and pressure of seawater.
