Definition of viscometer in US English:



  • An instrument for measuring the viscosity of liquids.

    • ‘The steady-shear surface viscosity was measured in a custom built magnetic needle viscometer.’
    • ‘Rheological properties were measured using a capillary viscometer recording shear stress - shear rate relationship.’
    • ‘The simple viscometer devised for these experiments may also prove useful in other contexts.’
    • ‘The Spectro technicians also use viscometers to test the viscosity of engine oil.’
    • ‘In addition, the cell orientation within the shear field varies in a random fashion due to cell-cell interactions when the hct is large as during preshear in the viscometer.’


Late 19th century: from late Latin viscosus ‘viscous’ + -meter.
