Red Sea High Accuracy Seawater Refractometer

Introduction

High Accuracy Seawater Refractometer! EASIER TO READ 0 to 40ppt

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/59F 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 coloration.

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, focussed to the relevant range for reef aquariums of up to 40pp
• Includes Integrated Automatic Temperature Compensation (ATC) for accurate measurement at standard ambient temperature.

  The PPT scale on Red Seas Seawater refractometer is calculated using an algorithm for seawater and therefore will give a reading of the Absolute Salinity of seawater.

The PPT scale on regular salinity refractometers are calculated using an algorithm for Brine. Using a Brine refractometer for Seawater will give an error of approximately 1.5ppt in the salinity reading.
