Precision optical instruments used for measuring concentrations of substances in aqueous solutions. When passing light through a liquid the refracted angle shows on the scale, determining the amount of dissolved solids in the liquid. Simply place one drop of your sample on the prism and read the results on the scales immediately! For sea water density with ATC. Range: 0-100% salinity, 1.000-1.070 (specific gravity), resolution 1% salinity, 0.001 (specific gravity). Drop Ship. |
