Maintain A Healthy Aquarium With Consistent Salinity Levels With The SciFish™ Dual Scale Salinity Refractometer!

Salinity is the most important measurement of seawater you can make for your tank. Having a proper and stable salinity in a saltwater aquarium lets your little fish live longer. Hydrometers are one of the tools that can measure salinity but they cannot be calibrated. Thus, notorious for being inaccurate.

The best way to measure salinity and specific gravity is to use a refractometer that provides accurate measurements, like this SciFish™ Dual Scale Salinity Refractometer!


  1. DUAL SCALE REFRACTOMETER: Measures in Salinity 0 - 100ppt and Specific Gravity 1.000 - 1.070
  2. AUTOMATIC TEMPERATURE COMPENSATION (ATC): Automated to provide accurate measurements on an easy to read scale even with temperature fluctuations.
  3. EASY TO USE: You just need 2-3 drops of solution on the prism and hold the refractometer to the light, then look through the eyepiece to read the results instantly and accurately. No lookup table needed and no waste!
  4. ADJUSTABLE FOCUS: Provides the sharpest display.
  5. IDEAL APPLICATIONS: Aquariums, marine monitoring, agriculture, gardening, and educational purposes like biology projects.
