DV2T Touch Screen Viscometer
The New DV2T Viscometer features a 5-inch color display to guide users through test creation and data gathering for fast and easy viscosity measurements. The DV2T also offers powerful new programming capabilities and results analysis including data averaging and QC limits with alarms. User instructions with multi-step test protocols can be created using the new Program Generator Software and uploaded to the DV2T through a USB Flash Drive (both included with instrument). Test Data can be recorded directly on a local printer or sent to a PC. Additional automated control and data collection can be achieved with optional RheocalcT software.

Dial Reading Viscometer
The original Brookfield Dial Reading Viscometer has been the lab standard used around the world since 1934. Current units have been been improved with a multi-speed electronic drive and ergonomically designed speed control knob so selection of any one of the 10 pre-set speeds (8 speeds on LVT models) is quick and easy. The direct-drive design results in extremely quiet operation and greater versatility while the universal power supply facilitates the use of worldwide power sources.
FEATURES & BENEFITS
- Continuous torque sensing capability
- Torque measurement accuracy: 1% of full scale range
- Repeatability: 0.2% of full scale range
- Easy speed adjustment and on/off control
- Compatible with all Brookfield accessories
- NIST traceable viscosity standards available
- Electronic drive means quiet, reliable operation
- Universal power supply worldwide compatibility
- 2-Year limited warranty
Falling Ball Viscometer
The Höppler principle is used to measure the viscosity of Newtonian liquid by measuring the time required for a ball to fall under gravity through a sample-filled tube that is inclined at an angle. The average time of three tests is taken; the result is converted into a viscosity value using a simple formula.
KF40 can be angled at 50°, 60°, 70° and 80°.
FEATURES AND BENEFITS
- Pivot bearing allows for quick and easy tube rotation – ideal for repeat tests
- Connection to circulating bath for temperature control of sample
- Set of six balls to test a wide variety of samples
- Complete with temperature probe
- Accuracy 0.5% to 2.0% depending on ball being used
Cone Plate Wells Brookfield Viscometer
The Wells-Brookfield Cone/Plate Viscometer gives researchers a sophisticated instrument for routinely determining absolute viscosity of fluids in small sample volumes. Its cone and plate geometry provides the precision necessary for development of complete rheological data.
PRINCIPLE OF OPERATION
The Wells-Brookfield Cone/Plate Viscometer is a precise torque meter which is driven at discrete rotational speeds. The torque measuring system, which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone, senses the resistance to rotation caused by the presence of sample fluid between the cone and a stationary flat plate.
The resistance to the rotation of the cone produces a torque that is proportional to the shear stress in the fluid. This reading is easily converted to absolute centipoise units (mPa·s) from pre-calculated range charts. Alternatively, viscosity can be calculated from the known geometric constants of the cone, the rate of rotation, and the stress related torque.
