Review on H B DURAC Percent Alcohol Proof Test: Reliable Substance Analysis Instrumentation by Justin Gerrero

I asked a question if this would work when listing the alcohol content of home brew beer. My answer is that this would give a proof result (10 proofs = 5%). I have ordered a product. What a waste of my money! I haven't read anything about beer. Rest assured, beer has a high alcohol content. I tried regular tap water and got the exact same readings! I've had it for a month and am trying different measurements in the brewing process. Always the same reading, nothing. I felt like I had too much time to go back and throw it away. nonsense, fraud! DO NOT BUY!
