Red Sea Seawater Refractometer

Red Sea’s Seawater Refractometer offers exceptional accuracy, for measuring the absolute salinity of seawater at a temperature of 25oC/77 0F. 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.

Features

  • 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) for more accurate salinity measurement (industry standard refractometers are calibrated for salt brine ).
  • Calibrated for seawater (NSW) at 25oC/77oF, the normal temperature range for reef aquariums
  • Easier to read, higher 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.
