This paper introduces the composition, function, technical performance, and measurement principle of Expendable Conductivity-Temperature-Depth (XCTD) Profiler, as well as the key technical problems has solved, and compares the technical parameters of domestic and foreign XCTD profilers used to deep sea. Based on comparative marine tests of SEB19 plus CTD and domestic XCTD profilers, it is found that the coefficients of correlation of both domestic and foreign XCTD profilers to CTD is above 0.999 and their measurement errors are almost the same in terms of single-profile measurement results, which leads to the conclusion that domestic XCTD profilers are comparable to similar products made in the US and other countries in both measurement accuracy and reliability.
