Introducing a New Range of Rotational Viscometers

Rotational viscometers, like those available from Gardco (USA), have become a standard in virtually all industries. They measure viscosity by sensing the torque required to rotate a spindle at constant speed while immersed in fluid. The torque is proportional to the viscous drag on the spindle; thus the sample viscosity.

Advantages include: User can calibrate viscometer, All Spindles made of 316 stainless steel, niversal power supply 110-230v 50/60 Hz, CE/UL/CSA Approved, Global service and support. 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 analysed.

Rotational viscometers are the industry standard in determining absolute viscosity of all types of liquids with viscosities as high as 320 million centipoise. Digital models are available for low - medium - high viscosity materials. Item #VI-B8325, VI-B8331, VI-B8337, and more.
