Review on Anpro Brix Refractometer for Homebrew - Dual Scale Specific Gravity 1.000-1.120 with Automatic Temperature Compensation 0-32% - Replacing Homebrew Hydrometer, M by Olusola Reid

I was surprised how easy it is. I got it to measure gravity at home and compared the readings using a standard hydrometer/cylinder/math method; the results were either identical or differed within 0.001 while the refractometer readings were slightly lower. For what I do, the ease of use of this thing is worth it. It only takes a few drops and here is your measurement. It's also very easy to calibrate, the instructions are clear and easy to follow, and it comes in a decent carrying case.
