Refractometer for Reading Salinity with Calibration Fluid

SKU: 205171


  • Excellent By Ryan on 11/13/2014

    This refractometer is so easy to use, and we've had it for three years! The calibration was extremely accurate and easily accomplished; although, we haven't had to calibrate very often. This meter is very accurate & easy to use! At the time we purchased, it was a BRS recommended product which has always been a great thing for confidence & assurance!!
  • Very Easy To Use By Jason on 11/10/2014

    I was worried when getting this, as I'm new to this hobby and mixing my own saltwater sounded intimidating at first. This refractometer is extremely easy to use and is exactly what I was hoping for. It's made mixing saltwater something that is easy to do, and I have confidence that the water is going to be spot on given it comes with calibration fluid.
  • Top notch By Matt on 11/5/2014

    Just stepped up from a little hydrometer that couldn't read the broad side of a barn. This new refractometer is great easy to use and accurate. (It's also pretty cool) best purchase I've made for my aquarium.
  • Works great! By Doug on 11/5/2014

    Much better than a hydrometer.
  • Okay product-exact reading difficult to get By jo on 11/2/2014

    Overall not a bad product. Except that it's pretty hard to see the exact reading since the one value tacs are just too small and close together even when adjusting the eye peice
  • very nice By Mike on 10/30/2014

    Very easy to read. Ease of use, and easy to calibrate.
  • Its a breeze By Randy on 10/23/2014

    Very easy to use and calibrate. Takes seconds to get your reading and then you can put it away until you need to take another measurement!
  • great product and quality By David on 10/13/2014

    This is the most accurate way to test specific gravity. Get rid of your inaccurate floater and replace it with this
  • Easy and Accurate By Michael on 10/9/2014

    I started off getting all my gear from a local fish store and had the basic salinity tester that sit on the table and gauges move. I upgraded to this one on the suggestion of a friend and glad I did. This thing is accurate and so easy to calibrate and read.
  • Great Refractometer just throw away the calibration fluid By Lukasz on 10/9/2014

    Ok, so the reefractometer is great, but the calibration fluid sucks. The fluid is supposed to be at 35 ppt. Mine wasn't and for a while there My tanks salinity was way way higher. Thank god I usually buy a second type of tester because I'm paranoid and test the tester. So the fluid was at 40 ppt instead of the advertised 35. Don't calibrate with fluid. Go buy some ro/di water and calibrate to 0, save yourself the pain
