Product Information
Built from the ground up by Red Sea, the new refractometer has a custom-designed seawater salinity scale and it is the first aquarium refractometer made to measure salinity at the same temperature as our tropical marine and reef aquariums.
Directly reads the absolute salinity of seawater at 25°c/77 0f ( no need for seawater or temperature compensation factors) Specifically designed for the ionic content of seawater (NSW) Calibrated for seawater (NSW) at 25oc/77of (most standard refractometers are calibrated at 15oc/59of )
