DV-79 rotational viscometer is a precision instrument for measuring the absolute viscosity of various Newtonian liquids and the apparent viscosity of non-Newtonian liquids. If used with a specific rotor, the rheology of non-Newtonian liquids can also be determined.
It has the advantages of easy use, stable performance and simple maintenance. It is suitable for measuring various greases, paints, inks, coatings, plastics, slurries, rubber, latex, detergents, resins, condensed milk, cream, drugs and cosmetics, etc. Fluid viscosity is an essential instrument for laboratories and analysis rooms in textile, chemical, petroleum, electromechanical, pharmaceutical, food, light industry, construction, and other industries as well as universities, scientific research units, and industry departments.

Instrument working principle
The instrument is driven by a miniature synchronous motor, which rotates at a constant speed of 750 r/min and is almost unaffected by changes in load and power supply voltage. The casing of the motor is installed in a suspended manner. It drives the drum to rotate through the rotating shaft. When the drum rotates in the liquid to be measured, it receives viscous resistance, which generates a reaction force to deflect the motor casing. The motor casing is connected with the two rods. The metal hairsprings installed front and back are connected, and the rotation of the housing causes the hairsprings to generate torque. When the balance of the hairspring and the viscous resistance torque is reached, the pointer connected to the motor housing points out a certain value on the dial. This value is proportional to the viscous resistance of the drum, so the scale reading times the rotational speed. The barrel factor represents the dynamic viscosity.
