Red Sea Seawater Refractometer Aragonite Model SL-600Red Seas Seawater Refractometer offers exceptional accuracy, for measuring the absolute salinity of seawater at a temperature of 25oC 770F. Most refractometers used within the aquarium hobby are not specifically designed for reef aquariums and use an algorithm for the measurement of brine (NaCl rather than seawater) and at a temperature of 15oC 59 0F rather than 25oC 77 0F. Thus, a measurement deviation of up to 1. 5ppt is possible, which can have a
