Beer Alcohol Meter 0.990-1.160 Portable 3 in 1 Alcoholometer Hydrometer Glass Tester 250mm Beer Homemade Winemaking Gadget Plastic Measuring Cylinder SetOOTDTY Descriptions:Similar in use for brewing hydrometer, but means in a different range. Using an alcohol meter is very simple. Pour a sample for testing in high glass or high chemical resistance plastic actuator, leaving enough room for the alcohol meter to disperse the liquid. To get the most accurate reading, try to keep the liquid as close to 68 °F (20 °C) as possible, as this is the temperature that your alcohol meter has been calibrated to (if your alcohol meter is calibrated to a different temperature, which should be listed on the meter, make sure your liquid is at the specified temperature). Place the alcohol meter in the sample and rotate it to remove any bubbles that may have been in the liquid, and it could potentially cause the alcohol meter to float slightly higher, resulting in a low reading. Read the sign where the liquid level crosses the stem of the alcohol meter. This is your alcohol percentage by volume.
