Overview
The AELAB LV-RV-HA-HB Series Rotary Viscometer provides fast and accurate viscosity measurement for fluid samples ranging from low to extremely high viscosity. Designed for laboratory and industrial environments, the instrument supports multiple rotors, adjustable rotational speeds, and optional adapters to extend measurement capability down to ultra-low viscosity levels.
The AELAB LV-RV-HA-HB Series rotary viscometer features intuitive operation, automatic calibration by computer, stable rotational speed, and strong anti-interference performance. The system displays viscosity, shear rate, and shear stress simultaneously, ensuring high comparability with imported viscometers used in quality control laboratories.
⚙️ Design & Construction
The AELAB LV-RV-HA-HB Series rotary viscometer is constructed with a rigid stand-mounted frame and precision motor drive. The instrument supports interchangeable Stainless Steel rotors (L1–L4 and R1–R7), enhanced ultra-low viscosity adapters, and optional constant temperature components to maintain stable testing conditions.

🔬 Working Principle / Testing Method
The AELAB LV-RV-HA-HB Series rotary viscometer measures viscosity by rotating a calibrated rotor at a controlled speed within the sample. The instrument quantifies the torque resistance generated by the fluid, converts the signal into viscosity values, and displays shear rate and shear stress for Newtonian liquid analysis.

💡 Key Advantages
- Wide viscosity measurement range up to 320,000,000 mPa·s
- Automatic calibration for each measurement range
- Stable rotational speed with strong anti-interference performance
- Simultaneous display of viscosity, shear rate, and shear stress
- Optional ultra-low viscosity adapter with minimum detection of 1 mPa·s
- Small sample adapters reducing sample volume to 7–11 mL
- Comparable data consistency with imported viscometers


🔗 Connectivity & Integration
The AELAB LV-RV-HA-HB Series rotary viscometer integrates two USB interfaces for direct connection to a computer and micro-thermal printer. Data and curves can be printed directly, supporting laboratory documentation and GLP-style record keeping.
