Measuring range: 0-40 vol%, 40-70 vol%, 70-100 vol%. Minimum scale: 1% vol. 2. 【1 0-50°C Thermometer with a reasonable temperature list】 The recommended use temperature is 20°C, but if the alcohol is not exactly 20°C, you can measure the temperature first and then read the value from the temperature list. 3. 【Easy calculation of alcohol content (ABV)】 Graded tapes help you see when brewing is complete and our crystal clear fonts are so easy to read. 4. 【Easy to use】 Similar to a brewing hydrometer, but measures in a different range. Using an alcohol meter is very simple. Pour a sample of the spirit to be tested into a tall glass or a very chemical-resistant plastic cylinder and leave enough space for the alcohol meter to distribute the liquid. 5. 【Measured alcohol range】 0-40 vol%, 40–70 vol%, 70–100 vol%, the minimum scale: 1 vol%, at the alcohol temperature 20 ℃. The delivery also includes a 0-50 ° C thermometer.
