The AELAB LVDV-1T / LVDV-2T touchscreen rotational viscometer integrates a 5-inch color touch screen with ARM technology and a built-in Linux system to perform fast, accurate viscosity testing. The AELAB LVDV-1T / LVDV-2T measures high-viscosity samples with stable rotational speed, supports automatic scanning of rotor and rotation speed, and displays viscosity curves and working parameters for controlled laboratory and industrial measurement workflows.
The AELAB LVDV-1T / LVDV-2T touchscreen rotational viscometer quantifies dynamic viscosity and supports kinematic viscosity calculation by density entry. Real-time temperature-time and viscosity-time curves are supported, and rheological curves of shear rate and viscosity can be displayed using optional data processing software, enabling repeatable viscosity testing in paint, cosmetics, ink, pulp, food, oil, starch, solvent adhesive, latex, biochemical products, and other high-viscosity industries.
