To measure the absolute viscosity a rotational viscometer is used. For non-Newtonian liquids a digital viscometer that applies a precise shear rate is needed. For laboratory viscosity measurement BYK-Gardner offers a comprehensive line of rotational viscometers. The viscometer product line can measure viscosity from a near water-like viscosity to a very high viscosity range for epoxy, sealants, and paste. To measure viscosity under a high shear rate Cone and Plate viscometers are available. The easy to use digital Stormer viscometer is also part of the rotational viscometer family.
