    INTRODUCTION The Brookfield DV-I+ Viscometer measures fluid viscosity at given shear rates. Viscosity is a measure of a fluid’s resistance to flow. You will find a detailed description of the mathematics of viscosity in the Brookfield publication “More Solutions to Sticky Problems” a copy of which was included with your DV-I+.

It is best to use a viscosity standard fluid that will be close to the maximum viscosity for a given cone spindle/speed combination.
  • Page 38 The guard leg was originally designed to protect the spindle during use. The first applications of the Brookfield Viscometer included hand held operation while measuring fluids in a 55 gallon drum. It is clear that under those conditions the potential for damage to the spindle was great. Original construc- tion included a sleeve that protected the spindle from side impact.
