Lactometer

Lactometer is an instrument for testing the quality of milk. One form of lactometer is a hydrometer to which is

attached a scale about five inches long, the zero of which marks the point to which it just sinks in water. Another

point on the scale corresponds to an average quality milk, and according as this mark sinks below or rises above

the level of the milk, the milk is said to be more or less diluted with water. The instrument is not scientifically

accurate, as the addition of either cream or water would cause the instrument to sink. Another form is a simple

glass tube graduated in 100 parts. New milk is poured in and left to stand. The cream rises, and its height gives the

number of parts of cream in 100 parts of milk. Sets of these tubes are used by farmers for comparing the quality of

the milk given by different cows.

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.

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

(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.
