GENERAL KNOWLEDGE

Detailed explanation-1: -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.

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: -Salinity is often derived from electrical conductivity (EC) measurement. EC is measured by passing an electric current between two metal plates or electrodes in the water sample and measuring how readily current flows between the plates.

Detailed explanation-4: -In the past century, only two major methods have been used in oceanography for the measurement of the seawater samples’ salinity: chlorinity titration and conductometry.
