Red Sea Seawater Refractometer

Red Sea Seawater Refractometer

Specifically designed for reef aquariums by one of the leaders in the reef aquarium field; Red Sea’s Seawater Refractometer offers exceptional accuracy for measuring the absolute salinity of seawater at a temperature of 25C/77 F. 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 significant adverse effect on coral growth and coloration. With this reef refractometer from Red Sea no further calibration or compensation for temperature is required making testing your aquarium salinity quick and easy.
