Definition of lactometer in US English:



  • An instrument for measuring the density of milk.

    • ‘Meucci's lactometer bears, in this framework, a notable importance, not much for the precision of measurement (somewhat impaired by the use of strong reagents, liable to partly solubilize the milk-solids) but because it was a forerunner of the following, more sophisticated, methods of determining the fat contents of milk.’
    • ‘The lactometer measures the specific gravity of milk.’
    • ‘Dr Aung Gyi said most of the lactometers on the Myanmar market are from China and India, although a small number of more advanced and more expensive European-made models are available.’
    • ‘Water in milk shows up in its lactometer reading and the change in freezing point.’
    • ‘The quizmaster, however, was least amused as degree coffee got its name after the lactometer used to measure the milk specific gravity (to detect adulteration).’
    • ‘Depending upon how much water is added to it lactometer will show lower and lower readings.’
    • ‘Sub-standard milk coming from other States can easily be stopped at the check posts by checking them using lactometers.’
    • ‘This describes a lactometer to be used for testing the quality of milk, and the illustration shows a rule of identical construction to the proof rule above, but with scales specific to the measurement of milk.’
    • ‘Always read the temperature of the milk first: the lactometer reading varies according to the temperature.’
