FAQ:
Q: What is the instrument used to measure salinity?
A: You can easily measure the salinity of sea/ocean water using an instrument called a refractometer, which measures the index of refraction of a particular substance. It is a device used in geology, medicine and agriculture.
Q: What is salinity and how is It measured?
A: Salinity is the measure of the concentration of dissolved salts in water. Salinity is measured indirectly by testing the electrical conductivity (EC) of the water.
Q: What is the unit of measurement for salinity?
A: Ocean salinity is generally defined as the salt concentration (e.g., Sodium and Chlorure) in sea water. It is measured in unit of PSU (Practical Salinity Unit), which is a unit based on the properties of sea water conductivity. It is equivalent to per thousand or (o/00) or to g/kg.
Q: What is used to measure salinity in water and soil?
A: 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.
