BS ISO 22804:2023

Marine technology. General technical requirement of marine conductivity-temperature-depth (CTD) measuring instrument. | Status: Current

1 Scope This document specifies the technical requirements to ensure consistent reporting on the test method, inspection rules, marks, packaging, transportation and storage of conductivity-temperature-depth (CTD) profilers. This document is applicable to marine fixed-point and mobile observation, monitoring platform and the various types of shipborne CTD measuring instruments.

NOTE A CTD directly measures conductivity, temperature, pressure of seawater. Depth is the conversion of pressure according to the Formula (C.1).
