Salinity meter is a very handy piece of equipment designed to measure the salinity of water. It’s very simple device with a salinity and temperature meter affixed to it to measure salinity of water at certain temperature. Modern development in technology has affected transformation in designs of the device. Today, salinity meters can be availed in highly sophisticated designs with advanced operating system and functional efficiency that ensure maximum accuracy in the measurements. The typical application of salinity meters are in the areas of water monitoring, seawater-prepared food solutions, breeding ponds, aquariums, and holding tanks. The salinity range of a standard salinity meter may hover between 0.1 to 10%.
