  • Page 4: Introduction

    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 temperatures. 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.
  • Page 5 Make sure to push up gently on the pivot screw that protrudes from the bottom of the viscometer. Connect the coupling link to the spindle and to the coupling nut. Place the insulating cap over the sample chamber inlet. Brookfield Engineering Laboratories, Inc. Page 4 Manual No. M/94-204-D1101...
