Description
Product Introduction
From manufacturing to actual application, coatings or inks often experience a range of shear rates. As typical non-Newtonian fluids, they exhibit varying viscosity characteristics under different shear rates.
It is generally accepted that coatings experience low shear rates during storage, transfer between containers, leveling, and sagging; moderate shear rates during pumping, dip coating, and low-speed mixing; and high shear rates during high-speed dispersion, roller coating, spray coating, and brush coating, where the shear rate typically reaches 9,000 s⁻¹. -1 ~12,000S -1 Therefore, to characterize the rheological behavior of coatings or inks at such high shear rates, a cone‑plate viscometer must be used for measurement.
Performance Features:
◆ 7-inch touchscreen, menu-driven operation, rich display content (including measured values, rotor type, rotational speed, shear rate, etc.), simple and convenient to use.
◆ The metal housing is both aesthetically pleasing and durable; the handle features an upgraded design for precise, rapid positioning and high reliability.
◆ The machine’s electrical components have been meticulously designed to deliver high reliability, precision, stability, and ease of use.
◆ ARM-based processor, delivering faster data processing speeds
◆ High-precision linear calibration prior to shipment, with the capability to interpolate multiple points, ensuring enhanced measurement accuracy.
◆ Continuously variable measurement of sample viscosity, allowing users to select different shear rates based on the sample’s actual application conditions.
◆ Viscosity measurements are displayed as continuous values, and multiple viscosity units can be freely interconverted.
◆ The instrument automatically issues an alarm when the measurement range is exceeded.
◆ High-speed data transmission interface, ensuring fast and stable communication between the instrument and the computer.
◆ Data storage and external USB drive data export functionality
◆ Built-in high-precision PT100 temperature probe, offering high temperature control accuracy and excellent stability.
◆ Integrated temperature calibration function ensures precise and reliable temperature control.
◆ Powerful calibration functionality: Users need only one bottle of standard oil; using the instrument’s built-in calibration menu, they can complete calibration quickly with simple操作.
◆ Optional data acquisition and programmable software are available for comprehensive analysis of the sample’s rheological properties.
