The rotational viscometer is an instrument that uses an internal rotating rotor for viscosity measurement. It can measure the viscosity of fluids and semi-solid materials. Its principle is based on Newton's fluid law and motor transmission technology.

It is understood that the central axis of the rotating rotor fixed in metal or plastic forms a straight line with the motor. Inside the rotating rotor, when rotating, the liquid or semi-solid material on the rotor also rotates. Due to the friction generated by the rotation of the rotor, the material forms a film on the surface of the rotor, and the adhesion of this film is proportional to the viscosity.

Then, according to Newton's fluid law, the liquid or semi-solid material forms a torque along the surface of the rotating rotor. This torque is proportional to the viscosity, and the motor transmission technology is used to convert the torque generated on the rotor into a voltage or current change, which can be converted into a readable digital display, so as to obtain an accurate measurement of the material viscosity. In practical applications, the test results are accurate, responsive and easy to operate.

rotational viscometer is widely used, including chemistry, medicine, pharmacy, food, paint, resin, cosmetics, coatings and other fields. Because the flow properties and viscosity of materials have a great impact on the production process, accurate measurement of material viscosity can not only effectively improve the quality problems in the production process, but also reduce production costs and improve product quality and market competitiveness.

In such a wide range of applications, it is very important to understand the principle of rotational viscometer. This not only helps to achieve accurate measurement and effective control of the production process, but also strengthens the in-depth understanding of product characteristics and material properties, and provides a better reference for product design and optimization.

rotational viscometer principle of learning and understanding, for the continuous development of modern industry and science and technology has an important role in promoting, to help us in production and scientific research towards a more efficient and sustainable new era of testing.
