Salinity refers to the amount of dissolved salts in a body of water. It is typically measured in parts per thousand (ppt) or grams per kilogram (g/kg). Salinity is an important factor in determining the density, freezing point, and boiling point of water. It also affects the distribution of marine organisms and the viability of certain industrial processes.
There are a number of different ways to check salinity. One common method is to use a refractometer. A refractometer measures the refractive index of water, which changes in proportion to the salinity. Another method is to use a conductivity meter. A conductivity meter measures the electrical conductivity of water, which also changes in proportion to the salinity.
