TRZBrix Refractometer with ATC, Handheld Refractometer,Dual Scale-Specific Gravity 1.000-1.130 and Brix 0-32% for Beer Wine and Fruit

I used this to check the gravity of my wort and it was flawless, easy to use and clean! Definitely would recommend this for all distillers.

This refractometer works fine, but is hard to use for measuring the Total Dissolved Solids (TDS) in coffee due to the measurement scale as the coffee measurement only uses the lower 5th of the scale, and thus is hard to read properly for an accurate measurement. Still beats buying the ~$200 coffee refractometers for a measurement you don't do very often.

Love this...I am a winemaker and it was always a long process to figure the brix and therefore the starting specific gravity of the grapes so that I could determine the ideal time for crushing. This awesome tool makes it a snap!

This is a well constructed unit that seems to work very well. I'm an engineer, so I'm usually pretty critical. When I received it, I tested it with distilled water. Bazinga! 0.0 brix. The instructions are a bit thin, but OK. Note that the "adjustment screw" is well hidden, under the black post that looks for all the world like a push-button. In order to use this unit, you need a really bright light. Regular room light won't work. Hold it out in the sunlight, or directly under a bright lamp. Comes with a handy cloth enclosure, three plastic droppers, a tiny screwdriver, and a cloth to clean the measurement surface.

Very simple to use. Saves a lot of time.

This seems accurate enough. It makes tracking your SG during the boil a cinch. They say it doesn't read fermenting beer. I haven't tried it. I use the hydrometer. There's more to drink after that way.

After adjusting has by working fine. Easy to use and read.

Checked it’s results against a hydrometer and it is spot on!
