Three measurement scales are available for salinity (Natural Sea Water Scale, Practical Salinity Scale and

Percent Scale).

NATURAL SEA WATER SCALE (UNESCO 1966)NATURAL SEA WATER SCALE (UNESCO 1966)

NATURAL SEA WATER SCALE (UNESCO 1966)

According to the definition, salinity of a sample in ppt is calculated using the following formula:

where:

- coefficient;

(sample) - uncompensated conductivity at T °C;

C(35,15)= 42914 µS/cm - the corresponding conductivity of KCl solution containing a mass of 32.4356 g

KCl / 1 Kg solution;

- temperature compensation polynom.

Note: The formula can be applied for temperatures between 10 °C and 31 °C.
