Many industries measure viscosity. “The use of viscometers runs the gamut,” says Robert McGregor, general manager of marketing and sales for high-end lab instruments at Brookfield Engineering (Middleboro, MA). “The biggest user is the quality control department using single-point measurement.” Research scientists also use viscometers to see how a material reacts to being sheared.

Viscometers measure viscosity, the resistance of fluids to flow or stress. In common terms, viscosity is related to a fluid’s “thickness”—a physical property of great interest to manufacturers of liquids, slurries, and pastes.
Useful viscometer/rheometer features that buyers should be aware of are temperature control, spindle rotational speed control, a range of sample holders, and ease of use.
Problem: Understanding the viscosity is a crucial aspect of manufacturing operations in many industries worldwide. In order to fulfill customer demands of product consistency and quality, viscosity measurement becomes even more important.
