Viscosity measuring devices from
TQC Sheen
Viscosity
Viscosity is the resistance of a liquid to movement or deformation. Testing the viscosity of a liquid or gas can provide information about how the sample will behave under certain circumstances. By measuring viscosity, for example, it is possible to predict how quickly oil will flow out of a spout or how quickly paint will dry.
The iP viscosity conversion table
To understand how the values measured in a viscosity test relate to the properties of the liquid being tested, you need to be able to convert them. When using a viscometer, the force required to move the liquid is usually converted into centistokes (cSt). In combination with the number of seconds, this allows the viscosity to be determined.
In our table you will find the formulae you can use to ensure that your sample complies with the relevant industry standards.
Key factors in the viscosity calculation:
- Temperature
- Cup size
- Selection of the oil
You can find more information about the factors to be considered in our practical table.

The most common methods of viscosity testing
The dynamic rotational viscometer method
This method is often used in production laboratories and as part of a robust quality control procedure. It measures the torque required to rotate an object that has been immersed in the sample liquid to be tested. The measurement indicates the viscosity of the sample.
Digital Krebs - Viscometer DV2300
This modern testing machine is based on the popular traditional KREBS method, which uses a weight-driven rotating paddle to measure the viscosity of the paint at a constant speed of 200 rpm. The torque generated is proportional to the viscosity of the sample and can be converted into viscosity (cP) or weight (gms) units.
Digital Cone & Plate Viscometer CP1 DV2500
Utilising high-precision microprocessor control, this device is both fast and accurate. It has a temperature control plate that allows the viscosity to be tested in a range between 5°C and 65°C and accurately controls the applied shear rate to 10,000S-1 (B.S./ISO requirements) or 12,000S-1 (ASTM).
Digital Rotothinner™ - Viscometer DV2700
A flexible two-in-one device that gives you a very high degree of control during the viscosity reduction process while providing a very useful stability analysis. It has three different spindles, one plate and two ball spindles, and offers three different measuring ranges up to a maximum of 350 poise.
Digital Gel Strength Tester - Viscometer DV2400
The digital TQC Sheen Gel Strength Tester is particularly suitable for assessing the yield strength and consistency of thick paints and other materials such as gels, fillers and more.
Digital multi-spindle viscometer DV2600
The TQC Sheen digital multi-spindle viscometer is the universal workhorse for viscosity measurement. In accordance with the Brookfield method, this multi-spindle viscometer offers a wide range of applications.

The falling ball viscometer method
In this method, the viscosity is determined by dropping a ball of known density through a sample liquid and measuring how long it takes to fall. A similar procedure can also be carried out with a falling piston.
The oscillating viscometer method
An oscillating electromechanical resonator is immersed in the liquid sample and measures the degree of damping of the liquid, allowing the viscosity to be determined.
The capillary viscometer method
This is one of the oldest methods of measuring viscosity, first developed in 1800. It measures the time it takes for a volume of liquid to travel the length of a capillary tube. They were known as Ostwald or Ubbelohde viscometers.
