Viscometers are instruments to measure the state of mixture of liquids or solids and viscosity of semisolids. General-purpose viscometers are called rheometers and are widely used. The resistance to deformation of a liquid expressed as a numerical value is called viscosity, and it can also be called viscosity coefficient or coefficient of viscosity. Analog types can perform simple measurements and digital types are used for precision measurements. Vibrating viscometers have high stability and minimal error. Rotational viscometers turn a rotor in a fluid to measure. And falling-ball viscometers drop a ball and measure fall speed. Touch panel type viscometers are used after being set by a PC or the like, so detailed measurement and analysis are possible. Viscometers each have their own features, so the measuring instrument used must be selected according to the object inspected.
