    Says it’s calibrated, but don’t take their word for it. Nearly killed some fish before the calibration fluid arrived. I’ve noticed that IT LOSES CALIBRATION fairly easily. Seems to measure accurately once calibrated, but it’s not holding the calibration from day to day, and I’m having to recalibrate every day or two. Not fun. Probably going to return and buy a more quality product. Or maybe keep as a backup to calibrate and test the quality product from time to time.

    This sure beats a hydrometer
    It’s quick, very accurate and cost the same as a hydrometer
    Out the box , mine was already preset to zero
    The only down side is you’ll need distilled water to adjust it later on so try not to drop or bang it

    This tool is now indispensable to me.
    I use this to test the water for my brine shrimp.
    I make small frozen brine shrimp cubes with those silicone molds/trays I get here on Amazon.
    My fresh water fish, no matter the size of my hand or as small as a neon tetra love them and they are more colorful than just feeding flakes.
    Being on a tight budget, I did not get calibration solution.
    I tested tap water, distilled water and bottled water and the tap water and distilled were were the same. The bottled water was a bit higher so, I calibrated with distilled water heated to 79 degrees F.
    I hatch my shrimp in ~25 – 30 just under 1.020.
    About 5 tablespoons of regular sea salt in just under a gallon of tap water with a touch of stress coat.
    I can easily and quickly check that my water (kept at 79 degrees F) is right on with this tool.
    My shrimp start hatching in ~12 hours under bright LED lights that are continually on.
    At 24 hours I put about 10 grains of Caputo yeast in with them and harvest at ~36 to ~48 hours based on my schedule. I prefer 48hrs the shrimp are a little bigger.
    I have in fact raised them to a week old but, it’s just not as efficient for me and requires maintenance.
    I use the same water twice, two batches of shrimp, after re-checking and adjusting water when needed.
    After two batches in same water, I replace the water with fresh.
    My harvests are great. I get about 40 cubes of pure shrimp (sucked up with a 2ml dropper right from shrimp net after rinsing) per ~3/4 gallon jug. (I use inverted gallon jug shape of a bleach bottle).
    After I get all I can out of net with the dropper, I swish the net in fish tank and the fish go nuts gobbling up the remaining hundreds if not thousands of live swimming shrimp I could net get out with the dropper!
    My hatch ratio is great and I depend on this tool to provide repeatable consistency.
    A+++

    This things awesome, super easy to use and calibrate. You may have to play around with it to get the bubbles out from between the layers but it works great and super easy to read.
