Rotational Viscometer - Digital Lab Viscosity Meter - 20-2,000,000 mPa·s - 0.3-60 rpm

The Master Science Rotational Viscometer is a spindle-type digital viscometer for measuring the dynamic viscosity of oils, paints, adhesives, food products, cosmetics and other liquids. A 16-bit microprocessor controls motor speed and calculates viscosity in real time.

The LCD shows viscosity, spindle speed, torque percentage, spindle number and the maximum viscosity measurable with the current spindle-speed combination, so operators can choose the right setting quickly.

Key Benefits

• Pick the right range fast: the display shows the maximum viscosity for each spindle and speed combination.
• Wide measuring span: the Master Science Rotational Viscometer covers from thin liquids to thick pastes up to 2,000,000 mPa·s.
• Stable speed: microprocessor speed control gives consistent shear conditions.
• Data transfer: RS232 output connects to a printer or PC.
• Temperature-controlled testing: optional thermostatic baths and heaters hold sample temperature.
