The density of which substance is measured by a lactometer?
A lactometer is used to measure the specific gravity (richness) of milk.
What is the structure of a lactometer?
A lactometer is a hydrometer that is calibrated specifically to determine the gravity or density of milk as opposed to water. In other words it determines the creaminess of milk. However, the gravity or density alone does not give a true indication of the quality of the milk. Other tests are required to determine fat content for instance. A hydrometer's structure consists of a float, usually made from glass, with a solid stem and two hollow bulbs at the bottom. The lower bulb is filled with mercury or lead shot to allow the hydrometer to float upright in the liquid being tested. The liquid is usually poured into a tall beaker and the float is lowered into it until it floats freely. It works according to Archimedes' principal that states that a solid floating within a liquid will be buoyed up by a force equal to the weight of the liquid that is displaced by the submerged portion of the solid. In other words, the less dense the liquid is, the more the float will submerge. The scale is typically written on the stem thus the density can be read directly according to where the surface of the liquid meets the stem. Lactometer scales are typically calibrated in 100 graduations, with 0 at the top of the scale (least creamy) and and 100 at the bottom (most creamy).

How do you read lactometer reading?
how to read the reading which is on the lactometer of zeal co.

What is lactometerfor what purpose and in what industry is the lactometer used?
lactometer is one kind of hydrometer used to determined the purity as well as specific gravity of milk
What is the principle of lactometer?
A Lactometer is a little glass instrument that tests the purity of milk based on density/buoyancy and works on the principle of the specific gravity of milk.
What is a lactometer and its uses?
a lactometer is generally used in dairy products .It is used to test the richness of dairy products especially milk because sometimes the products are found to be contaminated .
How is Archimedes principle based on lactometers?
Lactometer is a device used for finding the purity of a milk sample. It works on the principle of Archimede's principle that a solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced. If the milk sample is pure, then the lactometer floats on it and if it is adulterated or impure, then the lactometer sinks.
What is the use of meter?
Lactometer is used in measuring the density of milk.
How do you test the purity of milk using Archimedes principle?
Lactometer is a device used for finding the purity of a milk sample. It works on the principle of Archimede's principle that a solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced. If the milk sample is pure, then the lactometer floats on it and if it is adulterated or impure, then the lactometer sinks.
