1. an instrument used to measure the viscosity of a fluid
Usage: scientific; technical

Examples

• The lab technician used a viscometer to test the oil’s thickness.
• Different types of viscometers are designed for various fluid consistencies.
• The viscometer reading indicated that the paint was too thick for spraying.
• Quality control requires regular viscometer measurements of the syrup.
• The rotational viscometer provided accurate viscosity data for the polymer solution.
• Engineers calibrated the viscometer before testing the hydraulic fluid.
