Top 10 Salinity Refractometers

Are you looking for top 10 Salinity Refractometers available right now in the market? Then check out below, we researched and short listed best one here.

1. Aquatic Experts AccuBrate Refractometer

Our AccuBrate solution is specifically formulated to calibrate refractometers to accurately measure the salinity of saltwater, reef aquariums as well as natural seawater.


  • ACCURATE RESULTS! Our calibration solution is formulated from a high purity blend of salts to produce accurate readings every time. Refractometers must be calibrated often to obtain accurate readings. Note: RO/DI water will not calibrate your refractometer correctly. Always use Accubrate to ensure correct salinity readings – your aquatic friends will love you.
  • EASY TO USE: Our specially designed bottle has a built-in dropper tip which eliminates the need for a pipette. Simply squeeze a few drops of Accubrate directly from the bottle onto the refractometer’s prism slide and you are ready to calibrate your instrument. (Drops come out at a very controllable rate.)
  • LONG-LASTING: You need just 2 to 3 drops of our calibration solution to calibrate a refractometer. Using a few drops means our 60 ml bottle should last a very long time. For best results calibrate refractometer often to ensure accurate readings.
