Three scale hydrometer that gives an accurate gravity reading at 60 degrees F. Hydrometer also measures brix and potential ABV. Includes instructions for use.
A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water. The beer/wort to be tested is poured into a tall container and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer is noted. Hydrometers contain a scale inside the stem, so that the specific gravity can be read directly.
