    Lactometer is used for the measurement of density of milk.

    Lactometer is worked on the principle of ‘Specific Gravity’ by which it measures the estimated cream content of Milk. It is based on the Archimedes principle, states that “Solid suspended in a fluid will be buoyed up by a force equal to the weight of fluid displaced”.

    If a milk sample contains good amount of cream then lactometer floats lower. If the amount of water is high then lactometer sinks.

    Types of Lactometer:

    1. Mercury Lactometer: High precise readings and efficiancy
    2. Steel ball lactometer: Accurate and longer life

    Purity of milk is checked by Lactometer.
