Features

  • AccuBrate calibration solution is specifically formulated to calibrate hydrometers and refractometers to accurately measure the salinity of saltwater, reef aquariums as well as natural sea
  • Our calibration solution is formulated from a high purity blend of salts to produce accurate readings every time. Hydrometers 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.
  • 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 refractometers prism slide and you are ready to calibrate your instrument. (Drops come out at a very controllable rate.)
  • 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.

    • UPDATE: this fluid is spot on
Size: 60 ml
I am updating my review to 5 stars. This test fluid is right at 35ppt. my older fluids were testing to high so I thought this one was off. As a result my tank was pretty salty but got things back to normal now. Nothing happened that I could tell but it was good to get things back to 35ppt regardless. ... show more

    • Good product
Size: 60 ml
Only gave 4 stars because when I opened this it had seemed to leak all over everything else in the envolope. It was in its own bag but some of the fluid got out onto everything else. The cap seemed to be tight and it didnt seem to have much of anything missing from the 2oz bottle. It worked well for calibrating my refractometer ... show more
