1. Hydrometer

   A hydrometer or lactometer is an instrument used for measuring density or relative density of liquids based on the concept of buoyancy. They are typically calibrated and graduated with one or more scales such as specific gravity. A hydrometer usually consists of a sealed hollow glass tube with a wider bottom portion for buoyancy, a ballast such as lead or mercury for stability, and a narrow stem with graduations for measuring. The liquid to test is poured into a tall container, often a graduated cylinder, 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 correlates to relative density. Hydrometers can contain any number of scales along the stem corresponding to properties correlating to the density. Hydrometers are calibrated for different uses, such as a lactometer for measuring the density (creaminess) of milk, a saccharometer for measuring the density of sugar in a liquid, or an alcoholometer for measuring higher levels of alcohol in spirits. The hydrometer makes use of Archimedes' principle: a solid suspended in a fluid is buoyed by a force equal to the weight of the fluid displaced by the submerged part of the suspended solid. The lower the density of the fluid, the deeper a hydrometer of a given weight sinks; the stem is calibrated to give a numerical reading.

1. hydrometer

   A hydrometer is a scientific instrument used to measure the density or specific gravity of liquids. The measurement is typically based on the principle of buoyancy, where the hydrometer floats in the liquid and the degree to which it sinks or floats is used to calculate the liquid's density. It is commonly used in different industries such as brewing, wine-making, and petroleum industry.

1. Hydrometer

   A hydrometer is an instrument used to measure the specific gravity of liquids; that is, the ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. The liquid to be tested is poured into a tall container, often a graduated cylinder, 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 usually contain a scale inside the stem, so that the specific gravity can be read directly. A variety of scales exist, and are used depending on the context. Hydrometers may be calibrated for different uses, such as a lactometer for measuring the density of milk, a saccharometer for measuring the density of sugar in a liquid, or an alcoholometer for measuring higher levels of alcohol in spirits.

1. Hydrometer

   hī-drom′et-ėr, n. an instrument for measuring the density or specific gravity of solids and liquids by flotation, consisting of a weighted glass bulb or hollow metal cylinder with a long stem: a current-gauge.—adjs. Hydromet′ric, -al.—n. Hydrom′etry. [Gr. hydōr, water, metron, a measure.]

1. hydrometer

   An instrument constructed to measure the specific gravities of fluids. That used at sea for testing the amount of salt in the water is a glass tube containing a scale, the bottom of the tube swelling out into two bulbs, of which the lower is laden with shot, which causes the instrument to float perpendicularly, and as it displaces its own weight of water, of course it sinks deeper as the water is lighter, which is recorded by the scale.
