Product Description Material: Metal + Plastic Measurement Range: 0-80%. Min unit: 1% Accuracy: 1% Reference temperature 20 Accessories: 1*Measuring device 1*Pipette, 1*Cleaning cloth, 1*Screwdriver Used before calibrating the refractometer. 2. Please keep the refractometer dry and clean to make the instrument accurate and durable. Note: Not recommended for wine or other products high in sugar and other ingredients. 1. Simple and fast measuring alcohol refractometer, used to test the alcohol volume percentage of brandy, whiskey, vodka, etc. Note: Not recommended for wine or any other products high in sugar and other ingredients. 2. Accurate reading of ATC: Handheld alcohol refractometer with automatic temperature compensation (ATC), no longer have to worry about temperature changes affecting the reading accuracy. Refractometers used to measure alcohol volume percent take into account changes in ambient temperature and automatically compensate for them accordingly for accurate and repeatable measurements. 3. Unlimited use: It is a portable optical instrument for bartenders, wine merchants, food manufacturers, etc. The scale range is 0-80%V/V (V/V-alcohol volume percentage), graduation: 1%v/v. Fourth metal + plastic: The alcohol refractometer adopts non-staining, non-corrosive, non-reactive aluminum Made, easy to carry, scratch resistant and durable. 5.
