The DV-E combines economy and ease of operation with traditional
Brookfield excellence. The Brookfield DV-E has set a new world
standard for value in viscosity measurement. Simplified controls
allow operators to change test parameters quickly with the push of
a switch and turn of a knob.
The
digital display ensures easy and accurate readout of test results
for simultaneous measurement of viscosity and torque. Quality of
manufacture guarantees reliable performance and long life

A Sophisticated Rheometer With Easy-To-Use Intuitive Controls
and now with the added new capability to measure static yield stress
using vane
spindle geometry.
Why a Rheometer?
- A Rheometer measures and analyzes minute as well as broad changes
in a material's rheological structure - the way fluids and semi-solid
materials flow. This is accomplished by varying shear rates in micro
increments.
Features And Benefits
- Two instruments in one for easily
analyzing a material's yield stress and flow behavior by
measuring (1) the stress response versus strain during constant-rate
tests and (2)viscosity changes as a function of changing shear
rate, respectively.
- Continuous display of: Viscosity (cP
or mPa·s), Temperature (°C or °F), Shear Rate, Shear Stress,
% Torque, Spindle, Program status
- Also displays yield stress values
(Pa, dynes/cm², and % torque)
- 2600 speeds for incredible
characterization possibilities
- LV, RV, HA, HB and 5xHB torque
ranges available... Model
Selection Table
- Built-in RTD temperature probe for
sample monitoring
- Easy-to-use keypad with numeric
keys for stand-alone program entry
- Stand-alone programming: Enter
program requirements, start program, see the results on the
built-in display
- Download custom programs with RheoLoader
software (included)for viscosity tests and EZ-Yield software
(included) for yield stress tests
- Customizable options: time to
stop, time to torque, data averaging
