Overview: The NDJ-79 Rotary Viscometer is a precision instrument for measuring the absolute viscosity of various Newtonian liquids and the apparent viscosity of non-Newtonian liquids. For use with specific rotors, non-Newtonian liquids Rheological. It has the advantages of easy to use, stable performance, simple maintenance, etc. It is suitable for measuring various grease, paint, ink, paint, plastic, slurry, rubber, latex, detergent, resin, condensed milk, cream, medicine and cosmetics And other types of fluid viscosity, is the textile, chemical, oil, electromechanical, medicine, food, light industry, construction, and other industries as well as tertiary institutions, scientific research units, military departments of the laboratory, the analysis room of the necessary equipment.

How the instrument works:
The drive is driven by a miniature synchronous motor that rotates at a constant speed of 750 r / min and is almost unaffected by changes in load and supply voltage The motor housing is mounted in a suspension, When the drum rotates in the measured liquid to receive the role of viscous resistance, resulting in a reaction force to the motor housing deflection, the motor housing and two positive and negative installation of a metal gossamer connected to the rotation of the hairspring to produce Torque. When the gossamer example and the viscous resistance moment to balance, and the motor housing connected to the pointer on the dial to indicate a certain value, the value of the viscous resistance of the drum is proportional to, so read the scale by The upper drum factor represents the magnitude of the dynamic viscosity.
