AELAB Touchscreen High-Temperature Brinell Rotational Viscometer – RVDV/HADV/HBDV Series

The AELAB Touchscreen High-Temperature Brinell Rotational Viscometer (RVDV-1T-H, HADV-1T-H, HBDV-1T-H, RVDV-2T-H, HADV-2T-H, HBDV-2T-H) performs precise viscosity analysis for high-temperature melts using a coaxial center structure and small sample adapter. Each measurement requires a very small sample size while temperature control stabilizes quickly and accurately, enabling reliable viscosity testing for hot melt adhesives, asphalt, plastics, and related high-viscosity materials.

Designed for laboratory, industrial, and material development environments, the AELAB Touchscreen High-Temperature Brinell Rotational Viscometer integrates ARM technology with a built-in Linux system for intuitive test procedure creation, rapid data analysis, and stable rotational measurement. The 5-inch color touch screen provides rich graphical display, including dynamic viscosity, kinematic viscosity (with density input), temperature, shear rate, shear stress, and real-time viscosity curves.

⚙️ Design & Construction

The AELAB Touchscreen High-Temperature Brinell Rotational Viscometer uses a coaxial center structure to stabilize rotor alignment under elevated temperature conditions. The instrument supports standardized rotors No.21, No.27, No.28, and No.29, with optional ultra-low viscosity adapter rotor No.0 for molten low-viscosity samples. The compact footprint and integrated control architecture improve measurement repeatability while maintaining stable operation under wide voltage power supply conditions.

🔬 Working Principle / Testing Method

The AELAB Touchscreen High-Temperature Brinell Rotational Viscometer measures viscosity by rotating a calibrated rotor at a defined speed and quantifying the resistance torque generated by the sample. Rotational speed is regulated steplessly across 0.3–100 r/min (1T Series) or 0.1–200 r/min (2T Series), while the system continuously calculates viscosity, shear rate, and shear stress. Kinematic viscosity can be displayed when the sample density is entered, supporting broader rheological interpretation for melt processing and high-temperature formulation control.
