I. INTRODUCTION

The Brookfield DV-II Viscometer series has been the leading industrial viscometer since it

was first introduced in 1985. Brookfield has continued to develop and improve the DV-II to

provide the best value in the market for both quality control and research customers. The

Brookfield DV2T Viscometer continues in this tradition of innovation, quality and value. The

incorporation of a full color graphical touch screen display has allowed for a new and improved

user interface which preserves the single speed data collection methods while making all of

the advanced features of the DV2T readily available.
The Brookfield DV2T 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 science of

viscosity in the Brookfield publication “More Solutions to Sticky Problems”, a copy of which

was included with your DV2T.
This manual covers the DV2T Viscometer and the DV2T Extra Viscometer. The DV2T Extra is

a special package that includes several optional features to maximize the utility of the DV2T.

The DV2T Extra includes: Ball Bearing Suspension (not included in LV versions), EZ-Lock

spindle connection, Model Q Lab Stand, and RheocalcT Software. These differences are

detailed in the Components section of the manual. All references to the viscometer in this

manual will be made as DV2T. All of the optional features of the DV2T Extra may be added

individually to the DV2T Viscometer.

• The DV2T offers exceptional versatility in modes of control, allowing choice of traditional

standalone operation and automatic operation through programs downloaded from

the PC or with complete control by PC using Brookfield RheocalcT Software.

• The DV2T can be used as a traditional Brookfield viscometer for collection of single

speed viscosity data through the easy to use touch screen; just select the spindle and

speed and read the value from the display. [See Section II: Getting Started]

• The Brookfield PG Flash Software can be used to program the DV2T to control all

aspects of the test and data collection without the need for the operator to monitor

the instrument; just start the program and return to the printed test data (printer is

optional). [See Section V: PG Flash Software]

• The Brookfield RheocalcT Software will perform all control and data collection functions

of the DV2T from the PC while also providing a platform for advanced data collection
and analysis.

In any of these modes of control, the DV2T will provide the best in viscosity measurement

and control.

The principal of operation of the DV2T is to drive a spindle (which is immersed in the test fluid)

through a calibrated spring. The viscous drag of the fluid against the spindle is measured by the

spring deflection. Spring deflection is measured with a rotary transducer. The measurement

range of a DV2T (in centipoise or milliPascal•seconds) is determined by the rotational speed

of the spindle, the size and shape of the spindle, the container the spindle is rotating in, and

the full scale torque of the calibrated spring.
There are four basic spring torque series offered by Brookfield:
