    Rotational Viscometer Applications

    Tips: Functions of Viscometers

    Viscosity is an important physical parameters used to measure the liquid flow resistance ability. The measurement of viscosity is the important means of industrial process control, improving product quality and energy developing and saving. For example, for lubricating oil, viscosity is an important index to evaluate its lubrication ability. When lubricating oil passes through the surface of the lubricated moving pair, local high temperature and high pressure will oxidize the lubricating oil. Meanwhile, the addition of various impurities will also reduce the mobility of the lubricating oil, leading to the increase of viscosity. Therefore, the measurement of lubricating oil viscosity can reflect the quality state and residual life of lubricating oil.

    As a viscosity measuring instrument - viscometer, its application field is not only adhesives, coatings, lubricants and other chemical industries, but also widely used in toothpaste, shampoo and other daily chemicals. In addition, the viscometers are also widely used in yogurt, honey, tomato sauce, fruit juice and beverage and other food areas. In the production process, the viscometer is often used to detect the product viscosity so as to control the viscosity. The viscometer is indispensable to the production and product development tools. ATO digital rotational viscometer has stable and reliable quality, high accuracy and good repeatability. With the help of viscometer, the product can be controlled in the suitable viscosity range to fully play performance.
