The Rapid Visco Analyzer (RVA) is an increasingly popular and versatile tool used in the cereal and food industries worldwide to measure viscosity. As a result, a comprehensive, single-point resource to provide technical support for RVA users is needed. The RVA Handbook is just the tool that RVA users need.

This handbook aims to assist users in understanding the scope of applications available and as a tool to guide users in developing new applications or improving existing ones. It also assists in teaching how to interpret the results of RVA tests. Editors Graham B. Crosbie and Andrew S. Ross have gathered a group of expert authors who are recognized authorities in their disciplines and have applied the RVA in both conventional and innovative ways RVA users will find that this resource enhances their investment in the instrument.
