DEF Refractometer 0-40% AdBlue Diesel Exhaust Fluid Urea Concentration Refractometer Hand Held Refractometer with ATC for Automotive Diesel, AUS32 (Made of Copper Not Cheap Aluminum)

I want to point out that refractometer readings with alcohol present in the liquid need a conversion. I've seen a few reviews specifically related to homebrewing and how refractometer is inaccurately high. I suspect that the reviewer did not now this. With the conversion, I have found this Refractometer to be reasonably accurate. Do note that that conversion is based on the O.G. (so knowing how much alcohol is present).

Came fast and does what it's supposed to

I was a bit skeptical when I ordered this refractometer due to its low price, but it’s very nice. It’s important to avoid harvesting honey from uncapped cells if the moisture content is higher than 18% or 19%. This will tell you exactly how high the moisture content is and avoid fermented honey. It includes the solution needed to calibrate it. If you’re a serious beekeeper you need to have this on hand for honey harvest time!

Water content is critical in storing honey and this tool gives the assurance you need to safely jar honey.

Quality product

The instructions were missing. Was not easy to get a clear ready. Was easy to store and clean.

Must calibrate before use. Good quality for hobby reefers. Highly recommend.

Works great and a really nice item! Very happy with transaction and fast shipping! Would buy from again for sure.
