Overview
The Brookfield RVDV-E digital viscometer is a cost-effective laboratory instrument for measuring fluid viscosity across a broad range of applications. With 18 selectable speeds and interchangeable spindles, it delivers accurate viscosity measurements directly to an LCD display without manual calculations. The unit includes a spindle guard leg, lab stand, and protective carrying case—everything needed for immediate deployment in quality control, R&D, and production labs.
Key Features
- 18 Variable Speeds: 0.3 to 100 rpm speed range for comprehensive testing of Newtonian and non-Newtonian fluids
- High Accuracy: ±1% accuracy of any full scale spindle/speed viscosity range with ±0.2% repeatability
- LCD Display: Simultaneous display of viscosity in cP or mP·s, torque %, rpm speed, and spindle number with auto-determination of viscosity scale
- Automatic Range Selection: Turn a knob to choose RPM or spindle, and the viscometer automatically determines the full scale viscosity measurement range
- Complete Package: Includes spindles, spindle guard leg or lab stand, and carrying case
- Universal Compatibility: Full compatibility with all accessories from the Brookfield range
Technical Specifications
- Accuracy: ±1% of full scale range
- Repeatability: ±0.2%
- Speed Range: 0.3 to 100 rpm (18 speeds)
- Display: 16-character × 2-line backlit LCD
- Measurement Units: centipoise (cP) and millipascal-seconds (mPa·s)
- Power Supply: 115V / 60Hz single-phase AC
- Standard Spindle Types: LV (low viscosity), RV (medium viscosity), and optional HA/HB spindles
- Sample Chamber: 600 mL low-form beaker or equivalent (8.25 cm diameter)

Typical Applications
LV spindles measure low viscosity materials such as inks, oils, and solvents; RV spindles are for medium viscosity materials. The RVDV-E is widely used in pharmaceutical development, cosmetics formulation, food and beverage QC, paint and coating analysis, and polymer research. The direct digital readout and rapid speed selection make it suitable for high-throughput testing environments.
