Draft Survey Hydrometer
When carrying out a Draft Survey on bulk cargo vessels, it is important that the weight to volume relationship of supporting water is clearly understood and accurately reported.
This benchmark Glass Draft Survey Hydrometer was designed, in conjunction with S.G.S. Van Bree N.V., Antwerp, Member of the Societe Generale de Surveillance S.A., Geneva.
Each hydrometer is supplied complete with its own Calibration Certificate of Compliance as standard.
