Brookfield Model DV-III Ultra

Programmable Rheometer

 

The new value-priced DV-III Ultra Rheometer can operate as either a stand-alone instrument or under computer control to provide accurate and reproducible data for laboratory applications in R&D or QC.

The DV-III Ultra Rheometer has built-in rheological algorithms to allow rapid and repeatable material characterization, including flow curves, yield points, time dependencies and temperature profiles. Overall viscosity range capability is 0.1 to 800 million cP (mPa•s).

Over 2,600 speeds can be selected in steps as small as 0.01 rpm, shear rates from 0.002 to 1875 sec-1.Brookfield's optional Rheocalc software can be used to control the DV-III Ultra from a PC for complete automated laboratory analysis. Plus, the DV-III Ultra Rheometer can also store up to 10 customized programs in stand-alone mode for structured tests on the production floor or in the QC lab.

Up to 800 data points per test can be captured. Also included is the EZ-Yield Software for conducting yield stress tests.

The DV-III Ultra Rheometer works with Cone/ Plate and coaxial cylinder geometries as well as standard Brookfield

Features

For Value and Versatility

Stand Alone Operation
The DV-III Ultra can run in a programmable "stand alone" mode or under direct PC control. Tests that require multiple data points can be run and the data acquired, stored, displayed or printed with minimal operator involvement.
 
RHEOCALC Software
allows lab personnel to operate the DV-III Ultra from a PC so they can do other work while tests are running. After testing is complete, RHEOCALC can analyze the accumulated data. It can generate multiple plot overlays to compare test studies, print tabular data, run math models for comparative "fit" analysis, and perform other important time-saving routines.
 
User-Friendly Display and Keypad
An easy-to-read gas plasma display and intuitive tactile keys lead operators through test programs by providing visual guides for selecting geometry, rpm (speed), viscosity, temperature, shear rate, shear stress, % torque, and print and alarm status.
 
2600 Speeds at a Touch
from .01 through 250 rpm in steps as small as 0.01 increments.
 
Temperature Monitoring
The DV-III Ultra is supplied with an accurate RTD probe for monitoring sample temperature. Optional remote probes are available that provide temperature status and enable control of Brookfield accessories.
 
Serial and Parallel Ports
The DV-III Ultra has a parallel port to connect a printer and a serial port to connect a printer, PC or support Brookfield Programmable Controllers for Thermosel or TC-series Waterbath Accessories.
 
RHEOLOADER Software
This exclusive Brookfield software supplied with the DV-III Ultra allows you to create customized programs, each with as many as 50 commands. Once a program is downloaded from a host computer, up to 800 data points can be collected and automatically stored in DV-III Ultra memory.
 
EZ-Yield Software
Allows for yield stress testing.
 
Built-in Microprocessor
runs up to 10 complex test programs set from the DV-III Ultra keypad or downloaded from a PC using Brookfield RHEOLOADER software. Test data can be output directly to a printer in real time, viewed on the DV-III Ultra display, or stored in memory and downloaded to a PC later.
 
Built-in Math Models
Models provide data analysis without the use of external software. Casson Yield Values, NCA/CMA Casson (chocolate), Power Law, Bingham Plastic and IPC Paste Analysis calculations are included.
