Viscometers for Measuring Viscosity

Viscometers are used to measure the viscosity of your fluids, even foaming fluid, flowing fluid, low viscosity fluids such as sol and gel fluid, and more.

The viscosity of a fluid is a measure of its resistance to deformation by shear stress or tensile stress. For liquids, it corresponds to the "thickness" i.e example, honey has a higher viscosity or thickness than water.

Viscosity is due to friction between neighbouring parts of the fluid that are moving at different velocities. When fluid is forced through a tube, the fluid generally moves faster near the centre and very slowly near the outer edge, therefore some stress (such as a pressure difference between the two ends of the tube) is needed to overcome the friction between layers and keep the fluid moving. For the same velocity pattern, the stress required is proportional to the fluid's viscosity. A liquid's viscosity depends on the size and shape of its particles and the attractions between the particles.

We have two viscometers available:

SV10 Viscometer a Tuning-Fork Vibration Method (patents pending) which measures both Non-Newtonian and Newtonian fluids. Changing viscosity and temperature can be measured due to the wide measurement range from 0.3 to 10,000 mPa.s (cP), without replacing the sensor plates. The SV-10 measures viscosity by detecting the driving electric current necessary to resonate the two sensor plates at constant frequency of 30Hz and amplitude of less than 1mm. The WinCT-Viscosity, Data Collection, and Graphing software comes standard with the SV-10, letting you analyse your viscosity measurement.

Portable & Disposable Viscometer that works by measuring the falling time of the needle through a predetermined distance of the sample. There are automatically timed and manually timed (with a stopwatch) versions of this.
