The principle of digital rotary viscometer is based on Newton fluid model. It is mainly composed of rotor, motor and display. During the measurement, the liquid to be measured is put into the sampling chamber of the rotary viscometer, and then the motor is started to drive the rotor to rotate. When the rotor rotates, the liquid is forced to rotate with the rotor, resulting in shear force, which causes the flow inside the liquid.


According to Newton's fluid model, the viscosity of liquid is directly proportional to the shear force and inversely proportional to the shear rate. By measuring the rotor speed and torque, the viscosity of liquid can be calculated.

Digital rotary viscometer is an instrument widely used in the field of liquid viscosity measurement, which can be used to measure the viscosity of various liquids, including coatings, paints, chemicals, foods, medicines and so on. It plays an important role in the following aspects:

1. Quality control: Through the measurement of digital rotary viscometer, the viscosity of the product can be ensured to meet the preset standard, which is very important for the quality control of the product.

2. R&D and production: In the process of R&D and production, digital rotary viscometer can provide accurate viscosity data, which is very important for determining the fluidity, viscosity characteristics and quality standards of liquids.

3. Scientific research units: In scientific research units, digital rotary viscometer can be used to study the properties and behaviors of liquids, helping scientists to better understand the properties and laws of liquids.

In addition, digital rotary viscometer can also be used for viscosity measurement in oil, paint, slurry, textile, cosmetics and other production industries.
