Review on TRZ Refractometer: Accurate Measurements for Beekeeping, Honey, Condensed Milk, Fruit Jam, and Sugar Syrup - 10-32% Water Content + 58-90% Brix Sugar Baume - From Hamh Optics & Tools by Chad Carter

This refractometer is supplied with a solution to zero to the correct setting. It's very easy. It was nice to know that some of my unpackaged honey was at 17% and ready to be harvested. Save precious time by doing all my frames at once and my bees' efforts to close them. Has a zinc pouch for storage, comes with several drippers and good instructions. For the price and the 2 seconds it takes to test your honey, it's worth considering that my honey doesn't go bad with too much water. Don't let the price fool you. 💯👍👍👍👍👍Made in Germany.
