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.
Viscosity Cups / Bubble Viscometers
BYK-Gardner offers many choices to measure the kinematic viscosity of coatings, resins, and ink. A kinematic viscometer does not apply a shear force to measure the viscosity. The most common viscometers are the flow cups that include Zahn cup, Ford Cup, ISO Cup, and DIN cup. The bubble viscometer is also included in the kinematic viscosity category. All of these viscometers are easy to use and are reasonably priced. They are ideal for production control, field inspection, or laboratory use.
