High Performance Rotational Viscometer
Description & Specification
High Performance Rotational Viscometer
Categories:
Asphalt Binder Testing Equipment
Technical Specifications
Apparent viscosity of unfilled asphalt is evaluated by a rotational viscometer which measures the torque generated by a calibrated spindle rotating at a selected speed into a bitumen sample heated at precise temperature in the range between ambient temperature to 260°C. The measured relative resistance to rotation is converted, by a factor, in viscosity units, cP or mPa·s.
Main Features:
Selected speed r.p.m.
Selected spindle SP
Sample temperature °C or F
Density (introduced by the user) g/cm3
Viscosity reading cP (mPa·s) or cSt
Percentage of full scale %
Viscosity reading: dynamic viscosity (cP or mPa·s) or kinematics viscosity (cSt).
Shear Rate (with coaxial spindles) SR (s -1)
Shear Stress (with coaxial spindles) SS (N/m2)
Unit converter SI to CGS.
