DYMAX RF-20 SEA WATER REFRACTOMETER

Dymax RF-20 Refractometer is a scale device that helps to read salinity in water by using a calculation of mathematical algortihm that relates the measured refraction against its concentration for a specific liquid. This device is made of high quality anti-corrosion material that provides reliability and reads salinity instantly and accruately due to its high resolution display optimised for the relevant range of reef aquarims salinity.
