This model THE01507 works for alcohol testing (to test the alcohol concentration in the alcohol solution, not the grape wines or the other fruit wines). Its unit is W/W (Weight/Weight), the refractometers working temperature is suggested at 20C (about 18C to 25C). Measure the alcohol content accurately in seconds! All you need to do is manufacture a distillate of the liquids to be measured, and then place the distilled sample on the prism. Many of the refractometers on the market are made of plastic. However, people who work with alcoholic beverages or industrial fluids on a regular basis believe that metal refractometers provide more accurate measurements and that they simply stand up better over time and provides you with fast, accurate results - the very same characteristics that you get with all our Refractometers.
