Dial Reading Viscometers are low cost instruments suitable for a variety of quality control applications. Viscosity is measured by reading the number on the dial indicated by the red pointer. Brookfield provides a lookup table which converts this number to a viscosity value in units of centipoise (cP) or milli-Pascal seconds (mPa·s). The choice of series (LV, RV, HA, HB) is based on the viscosity of the product(s) to be measured.

DV-I+ Serial Viscometers

DV-I+ Viscometers provide digital display of viscosity (cP or mPa·s) and % torque with analog signal output (0-1vdc). These instruments have 18 speeds. All instruments are shipped with spindles (4 for LVDV-I+, 7 for all others), Lab Stand and Carrying Case.

Programable DV-II+ Viscometers rvdv-II+ brookfield viskozimetre

Programmable DV-II+ viscometers include DV-I+ features and add temperature measurement and display, RS232 signal output (allowing use with Wingather software) and display of shear rate and shear stress when using coaxial cylinder or cone and plate geometry. All Programmable DV-II+ Viscometers feature 54 rotational speeds. These instruments are now programmable with "DVLOADER" software, supplied with all instruments.

DV-E Economy Digital Viscometers

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.

DV-III Programable Rheometers

DV-III Programmable Rheometers offer 2,500 rotational Speeds (from 0.1 RPM through 250 RPM in 0.1 RPM increments), PC control with optional Rheocalc Software (available in DOS or Windows versions) and test program storage with or without PC control. Similar to DV-II+, DV-III measures viscosity and temperature simultaneously and displays shear rate and shear stress when using coaxial cylinder or cone/plate geometry. The DV-III features a 4 line gas plasma display for measurement parameters and may be programmed in stand-alone mode from the keypadwithout a computer. The instrument will store 10 test programs, each of which may have up to 25 steps. Once written, the Rheometer will run the test and if equipped with a serial printer, print the results automatically and store the results. Download to a printer or PC can occur whenever the user chooses. DV-III Rheometers are supplied with spindles for use in a 600 ml Low Form Griffin Beaker (4 with LVDV-III, 7 with all other models), Power Base, Laboratory Stand and Carrying Case. 

KU-1+ Digital Viscometers

The new and improved KU-1+ provides continuous sensing and direct display of viscosity in Krebs units. Major Benefits And Features Measures paints, coatings and related materials (inks, oils, pastes, etc.) Used in QC and R&D LED Digital Display Krebs Units (increased resolution in 0.1 KU increments) Grams (in 1 gm increments) Expanded measurement range (40 to 141 KU; 32 to 1099 g) Accuracy to ±1% of range Reproducibility to ±0.5% of range Output to parallel printer for automatic test documentation Easy to use; no weights; simplifies an established test procedure Compatible with industry specification (ASTM D562) Allows rapid sample measurement to determine required consistency Base accomodates standard pint, 1/2 pint, and quart cans Still modestly priced

CAP-1000 and CAP-2000 High Shearrate Digital Viscometers

The CAPviscometer is designedfor high shearrate 150 to 26,600 sec-1)tests of materials. Primary applications include paints, inks, resins, and coatings (simulating rolling, brushing and spraying ). Theease of usemakesthis an ideal instrument for Quality Control orResearch and Developmentapplications requiringquick and easytesting (sample can be loaded, a reading taken and the instrument cleaned and made ready for the next test in less than 2 minutes!). Choice of two separate temperature ranges is available. Low temperature: 5°C to 75°C. High temperature: 50°C to 200°C. Please specify when ordering. Six cone spindles are available depending on viscosity range required. One spindle is automatically included with the CAP Viscometer. Refer to the following table to make your selection:

Plate and Cone
Brookfield Cone and Plate Viscometers/Rheometers are instruments designed to measure small sample volumes at defined shear rates. These instruments are used with a circulating water bath for precise temperature control. Advantages include: Small Sample Volume: 0.5, 1.0 or 2.0 ml depending on cone spindle choice. Very Good Temperature Control: The small volume of sample relative to the mass of the cone and plate means that sample comes to test temperature immediately. Wide Measurement Range: Cone/Plate instruments are available in all the standard Brookfield torques (i.e. LV, RV, HA, HB). The 5 available Cone Spindles provides great versatility.

High Pressure and PVS Rheometers For High Heating

The PVS is a dynamic coaxial cylinder, controlled shear rate rheometer allowing quick and easy viscosity measurements under pressure at temperatures where sample boil-off is a problem. The PVS can be used to simulate process conditions for small fluid samples in a laboratory benchtop environment. Applications include chemical compounds containing volatile materials, oil industry, drilling muds and fracturing fluids, processed foods, polymers and paints. Any test sample requiring absolute viscosity measurement under totally enclosed conditions is a viable candidate.
