Explore Advanced Rotational Viscometers from Qualitest

Rotational Viscometers are one of the most sought after Qualitest products in the market. We have continued to meet client expectations through our best in class technology and customer service. Designed to measure viscosity by sensing the torque required to rotate a spindle at constant speed while immersed in fluid, our viscometers are highly customizable and meet customer needs in various industrial settings.

Rotational Viscometers offer several advantages:

•  The continuous rotation of the spindle allows measurements to be made over time, permitting analysis of time-dependent fluids.
• The rate of shear is constant, so both Newtonian and non-Newtonian fluids can be tested.
• By rotating the spindle at several different speeds, shear dependent behavior can be analyzed.
• Rotational viscometers are the industry standard in determining absolute viscosity of all types of liquids with viscosities as high as 320 million centipoise. Qualitest offers digital models for low– medium – high viscosity materials.

While various models of viscometers are recommended for high, medium, and low viscosity applications, these designations are intended only as guidelines. Multiple speeds and interchangeable spindles on each viscometer provide many viscosity ranges for flexibility in application. Selecting the correct model will ensure maximum sensitivity and accuracy in the measured viscosity range. Some of the factors to consider in selecting a viscometer are: the viscosity range of the samples, how much sample is available, do you need to monitor the temperature, and do you need to record the viscosity values.

Qualitest, with its trusted supplier network, is well aware of the various testing requirements that may arise in different industries. Besides efficient logistics and a high level of standards, we guarantee the best prices as well. Our products are built to last and various government agencies, educational institutions, and private businesses have benefitted from our advanced state-of-the-art testing products.
