⚙️ Design & Construction

The AELAB RVDV-1T touchscreen viscometer is a bench-top rotational viscosity measurement instrument engineered for routine laboratory and industrial quality control. The RVDV-1T uses a 5-inch color touch screen for direct parameter setting, method selection, and curve viewing. The rotor system supports R2–R7 standard rotors and optional rotors/adapters for ultra-low viscosity and small-volume testing, enabling broad sample compatibility across high-viscosity and controlled-volume applications.

🔬 Working Principle / Testing Method

The AELAB RVDV-1T rotational viscometer measures dynamic viscosity by rotating a defined rotor at controlled speed and quantifying the resistance torque generated by the sample. The instrument calculates viscosity at selected speed points and displays viscosity, shear rate, and shear stress. The RVDV-1T supports automatic scanning to identify recommended rotor-speed combinations and displays time-viscosity curves and optional temperature-viscosity curves for process and formulation monitoring.
