Red Sea – Refractometer

Red Seas Seawater Refractometer offers exceptional accuracy, for measuring the absolute salinity of seawater at a temperature of 25C/77F.

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 15C/59 F rather than 25C/77F. Thus, a measurement deviation of up to 1.5ppt is possible, which can have a significant adverse effect on coral growth and colouration.

Main features of Red Seas Seawater Refractometer include:
– Directly reads the absolute salinity of seawater at 25C/77F ( No need for seawater or temperature compensation factors)
– Specifically designed for the ionic content of seawater (NSW) for more accurate salinity measurement (industry-standard refractometers are calibrated for salt brine ).
– Calibrated for seawater (NSW) at 25C/77F, the normal temperature range for reef aquariums (most standard refractometers are calibrated at 15C/59F ).
– Easier to read, higher resolution display, focused on the relevant range for reef aquariums of up to 40ppt
– Includes Integrated Automatic Temperature Compensation (ATC) for accurate measurement at standard ambient temperature.
