Red Sea Seawater Refractometer Information


Product Manuals & Documentation

High Accuracy Seawater Refractometer!

Red Sea’s Seawater Refractometer offers exceptional accuracy, for measuring the absolute salinity of seawater at a temperature of 25°C/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 15°C/59°F rather than 25°C/77°F. 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 25°C/77°F ( 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 25°C/77°F, the normal temperature range for reef aquariums (most standard refractometers are calibrated at 15°C/59°F ).
  • 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.
Red Sea’s Refractometer display
The PPT scale on Red Sea’s 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.

Comments: this unit is great. The large scale for marine salinity makes reading the values super easy. So far the temperature for calibration seems to keep the need for calibration much less frequent. I have been using refractometers for 4 years now, and this one makes the job so much faster and easier to get accurate readings.

Experience Level: Expert


Comments: Very good product: the fact that it is meant to be read for 25 degrees (most other products are set to 20) makes it a breeze to calibrate with reference solutions. The screen itself is very clear to read. The range is limited to 1010-1030 sg, making it perfect for the kind of salinity we are targeting in reef aquarium, aka easier to get a precise reading! The only annoying thing is the protection for the little "setup screw" would be better if it was attached to the body, it looks like it could easily get lost.
