Question

explain how lactometer works.

Answer 1

A lactometer is used to check purity of cow's milk. ... Milk is poured in and allowed to stand until the cream has formed, then the depth of the cream deposit in degrees determines the quality of the milk. If the milk sample is pure, the lactometer floats; if it is adulterated or impure, the lactometer sinks.

Answer 2

A lactometer measures the density of milk.

Lactometer indirectly measures the cream content of milk. The more cream, the lower the lactometer floats in the milk.

A lactometer is a little glass instruments that tests the purity of milk based on density/buoyancy and works on the principle of the specific gravity of milk.
