    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.

    LACTOMETER

    Here below some steps mentioned for milk testing –
    Step 1- Whenever you want to test the milk purityArticle Submission, you just put the instrument or lactometer in milk.
    Step 2- If it sinks up to the mark ‘M’ which mentioned at lactometer that means milk is pure or if not that means milk is impure.
    Step 3- If the milk is mixed in water then it would sink higher then marked ‘M’.
    Step4- If it stands at the mark 3 that means milk is 75% pure and respectively 2 for 50% purity and 1 means 25% purity.
