I. INTRODUCTION
The Brookfield Thermosel System consists of a Brookfield Viscometer or Rheometer with related
accessories to accurately measure the viscosity of liquids at elevated tem peratures. Viscosity
measurements are obtained using coaxial cylinder geometry. Temperature is controlled by a solid
state, triac output, Proportioning Controller which maintains the spindle, chamber, and sample
material at the desired temperature.
The system is designed for measuring liquid viscosities over a temperature range from 40°C (104°F)
to 300°C (572°F). The designed viscosity range is from 3 cP to 80,000,000 cP depending upon the
vis cometer and SC4 spindle used.
Please note that all references made herein to digital viscometers would also apply to DV-III+
Rheometers and DV-III Ultra Rheometers.
