Review on SMARTSMITH Alcohol Refractometer - High Accuracy Spirit Alcohol 🍹 Volume Percent Measurement with automatic temperature compensation (ATC), 0-80% v/v Range by Amy Collins

We harvested 30 Sugar Maple trees in the yard and in the woods. The refractometer works well to help us know when our sap has turned into maple syrup. I love that you only need to use a tiny but liquid amount to get a reading. I would like more detailed instructions. I don't think I could figure out how to use it alone. However, my husband used to be a chemist and used refractometers all the time. He showed me how to use it. It is important to realize that these less expensive refractometers have a limited range. The one you buy for honey and maple syrup won't work for wine or spirits. Revain's website clearly states that certain refractometers are suitable for certain purposes. Our youngest son uses a refractometer to make spirits. He has one with a different range.,
