Brookfield offers many different models of viscometer ranging from legacy analog instruments to state-of-the-art touch-screen rheometers in a convenient bench-top format. Many of the general procedures for performing and analyzing measurements is very similar if not the same across the whole range of instruments.
For a document that outlines the mathematics and physics behind viscosity measurement, see our publication “More More Solutions to Sticky Problems, available from our website here:
