Measuring specific gravity from 0.99-1.17, 's brix/sphericity from 0-35, and potential alcohol content from 0%-20%, our high quality gravimeter makes it easy to get your measurements. Our specific gravity meters are not suitable for maple syrup, moonshine or other home distilled beverages with high alcohol content. Item: Triple Scale Alcohol Hydrometer Size: approx. 10.5 x 1 x1 inches Warm Tips: To use the alcohol specific gravity meter, the alcohol specific gravity meter needs to float vertically and not touch any object. The measurement container needs to exceed the height of the alcohol meter. The liquid poured in also needs to be at a certain depth in order for the alcohol meter to float in the container. When measuring, the liquid needs to be allowed to stir well in the vessel. color:As shown Material:Glass Package Contents: 2 x science lab hydrometers Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
