Natural Sea Water Scale
The Natural Sea Water Scale extends from 0 - 80.0 g/L. It determines salinity
based upon a conductivity ratio of sample to “standard seawater” at 15 °C.
Where R

is the conductivity ratio and salinity is
defined by the following equation:
S = - 0.08996 + 28.2929729R

+ 12.80832R
