The seawater refractometer offers exceptional accuracy because it uses a specific algorithm developed to measure the absolute salinity of seawater at a temperature of 25°C.
The refractometer is an optical instrument that uses refractive index measurement to determine the salinity of natural and artificial seawater, seawater or brackish intermediates.
The Aqua Medic LED Refractometer is a precision optical instrument for the exact determination of the amount of salt in saltwater aquariums . A few drops allow the determination of the salt concentration in a few seconds. It can be read either as absolute quantity of salt (salinity) in ‰, ppt or as density.
