Detailed explanation-1: -Salinity. Salinity is the measure of the number of grams of salts per kilogram of seawater, which is expressed in parts per thousand. Parts per thousand can be defined as how many parts, or grams, of salt there are per thousand parts, or kilogram (1, 000 g), of seawater. The symbol for parts per thousand is ‰.

Detailed explanation-2: -Water and soil salinity are measured by passing an electric current between the two electrodes of a salinity meter in a sample of soil or water. The electrical conductivity or EC of a soil or water sample is influenced by the concentration and composition of dissolved salts.

Detailed explanation-3: -salinometer, also called salinimeter or salimeter, device used to measure the salinity of a solution. It is frequently a hydrometer that is specially calibrated to read out the percentage of salt in a solution.
