Supply capacity 10 SETS/MONTH
KN-4402 Rotational Viscometer for Asphalt Viscosity conforms to ASTM D4402 Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer. A rotational viscometer is used to measure the apparent viscosity of asphalt at elevated temperature. The torque on the apparatus-measuring geometry, rotating in a thermostatically controlled sample holder containing a sample of asphalt, is used to measure the relative resistance to rotation. The torque and speed are used to determine the viscosity of the asphalt in pascal seconds, millipascal seconds, or centipoise.

Features
Adopts ARM technology, built-in Linux system. Operation interface is simple and clear, through the creation of testing procedures and data analysis, fast and convenient viscosity testing
Accurate viscosity measurement: each measuring range is automatically calibrated by computer with high precision and small error
Display rich: in addition to viscosity (dynamic viscosity and kinematic viscosity), there are temperature, shear rate, shear stress, measured value as a percentage of the full range value (graphic display), range overflow alarm, automatic scanning, maximum measurement range under the current rotor speed combination, date, time, etc. The kinematic viscosity can be displayed under the known density to meet the different measurement requirements of users
Fully functional: can be timed measurement, self-built 30 groups of testing procedures, access to 30 groups of measurement data, real-time display viscosity Curves, printed data, curves, etc.
Stepless speed regulation
Shows the curve of shear rate to viscosity: can set the range of shear rate, real-time display on the computer; can also show the curve of time to viscosity
Measurable in a very large range from 50 to 80 million MPA.S, samples that can meet various high viscosity high temperature melts (e.g. hot melt adhesive, asphalt, plastics, etc.)
Optional ultra-low viscosity adapter (rotor 0) can also measure the viscosity of paraffin wax, polyethylene wax if molten sample.
