In view of the adverse environment of sea-water index detection,an on-line detection system using the wireless sensor networks for real-time detection of sea water index is proposed.

The series of China standard seawater are the national secondary reference mater ial of China [GBW (E) 130011], which is extensively applied in the in-situ ver ification of the salinity or conductivity sensors and the verification or calibr ation of lab salinometer This paper introduced mainly the preparation and unce rtainty analysis of the series of standard seawate
