High Performance Rotational Viscometer

High Performance Rotational Viscometer

Description

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. 

 

• Selected speed r.p.m.
• Selected spindle SP
• Viscosity reading cP (mPa·s) or cSt
• Percentage of full scale %
• Sample temperature °C or F
• Shear Rate (with coaxial spindles) SR (s -1)
• Shear Stress (with coaxial spindles) SS (N/m2)
• Density (introduced by the user) g/cm3
• Viscosity reading: dynamic viscosity (cP or mPa·s) or kinematics viscosity (cSt).
• Unit converter SI to CGS.
• Program features:
• Time to torque & Time to stop
• 9 working memories
• Customizable speed options
• Multistep
• Ramp
• AUTO-TEST: automatical internal viscosimeter checking
• AUTO-RANGE: full scale range for combination spindle speed.
• Temperature reading by PT100.
• User-enabled viscosity and temperature calibration.
• 10 language options.
