Red Sea’s Seawater Refractometer offers exceptional accuracy with seawater composition such as that found in marine aquariums.

available to order

Most refractometers used within the aquarium hobby are not specifically designed for reef aquariums seawater but for measurement of brine (NaCl plus water – rather than seawater) and at a temperature of 15ºC rather than 25ºC. Thus, a measurement deviation of up to 1.5ppt is possible, which can have a significant adverse effect on coral growth and coloration.

Main features of Red Sea’s Seawater Refractometer include:

  • Directly reads the absolute salinity of seawater at 25ºC (no need for seawater or temperature compensation factors)
  • Specifically designed for the ionic content of seawater (NSW) for more accurate salinity measurement (industrial refractometers are usually calibrated for salt brine).
  • Calibrated for seawater (NSW) at 25ºC, closer to the usual temperature range in reef aquariums (most standard refractometers are calibrated at 15ºC).
  • Easier to read with its high resolution display, focussed to the relevant range for reef aquariums of up to 40ppt
  • Includes integrated Automatic Temperature Compensation (ATC) for accurate measurement at standard ambient temperature.
