Rotational Viscometer for Asphalt Viscosity
Rotational Viscometer for Asphalt Viscosity TT-4402
Rotational Viscometer for Asphalt Viscosity TT-4402 complies with the ASTM D4402 Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer.
Rotational Viscometer for Asphalt Viscosity TT-4402 utilizes a rotational viscometer to gauge the apparent viscosity of asphalt at elevated temperatures. By measuring the torque on the apparatus-measuring geometry as it rotates within a thermostatically controlled sample holder containing asphalt, the relative resistance to rotation is determined. This torque and speed combination allows for the determination of asphalt viscosity in pascal seconds, millipascal seconds, or centipoise.
1. Utilizes ARM technology and a built-in Linux system for efficient operation. The interface is user-friendly, allowing for quick and convenient viscosity testing through the creation of testing procedures and data analysis.
2. Ensures accurate viscosity measurement with each measuring range automatically calibrated by the computer, resulting in high precision and minimal error.
3. Offers a rich display including dynamic viscosity, kinematic viscosity, temperature, shear rate, shear stress, measured value as a percentage of the full range value (graphical display), range overflow alarm, automatic scanning, maximum measurement range under the current rotor speed combination, date, time, and more. Kinematic viscosity can be displayed under known density to accommodate various measurement requirements.
4. Provides comprehensive functionality such as timed measurement, the ability to create 30 groups of testing procedures, access to 30 groups of measurement data, real-time display of viscosity curves, and the option to print data and curves.
5. Features stepless speed regulation for precise control.
6. Displays the curve of shear rate to viscosity, allowing users to set the range of shear rate and view real-time display on the computer. Additionally, it can show the curve of time to viscosity.
This viscometer is capable of measuring in a wide range from 50 to 80 million MPA.S, making it suitable for various high viscosity and high-temperature melts such as hot melt adhesive, asphalt, plastics, and more. An optional ultra-low viscosity adapter (rotor 0) enables measurement of viscosity for molten samples like paraffin wax and polyethylene wax.
