How does the lactometer work?

Lactometer is a small glass instrument that is used to test the purity of the milk. It works on the principle of specific gravity of milk (Archimede’s Principle). It measures the relative density of milk with respect to water. If the specific gravity of a sample of milk is within the approved ranges, the milk is pure.

How does a lactometer look?

Lactometer is a cylindrical vessel made by blowing a glass tube. One side of glass tube looks like a bulb filled with mercury and another side is thin tube with scale.
