Hand Held DEF AdBlue Refractometer Tester for Urea Concentration in Diesel Exhaust Fluid Aqueous Urea Solution with ATC Automatic Temperature Compensation Measuring Range 0-40% (Copper)

Came fast and does what it's supposed to

Quality product

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).

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

I dislike the fact that the first order came with a broken case with no product ,had to order a replacement, luckily it came with a good case and product. I use it for coolant in a machine shop where I work!

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

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

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!
