Yetuo NDJ-79 pointer viscometer
Model: NDJ-79
Product Overview:
A pointer viscometer is a precision instrument used to measure the absolute viscosity of various Newtonian liquids and the apparent viscosity of non Newtonian liquids. If used with specific rotors, the rheological properties of non Newtonian liquids can also be measured. It has the advantages of easy use, stable performance, and simple maintenance, and is suitable for measuring the viscosity of various fluids such as oils, paints, inks, coatings, plastics, pastes, rubber, latex, detergents, resins, condensed milk, cream, drugs, and cosmetics.
Product features of Yetuo NDJ-79 pointer viscometer
● Constant speed power system
The micro synchronous motor is driven at a constant speed of 750r/min and is installed in a suspended manner to ensure that its operation is not affected by power fluctuations and load changes, resulting in high stability;
Accurate torque balance reading
When the torque of the balance spring is balanced with the viscous resistance torque, the pointer connected to the housing directly displays the proportional value on the dial, indicating the magnitude of the resistance;
Resistance deflection measurement principle
The electric motor drives the rotating drum to immerse in the measured liquid through the rotating shaft, and the viscous resistance of the liquid acts on the rotating drum, pushing the motor housing to deflect and generating reverse torque through the linkage of the double balance spring;
● Data conversion and anti-interference capability
The dynamic viscosity value is obtained by multiplying the scale reading by the rotary cylinder factor. The constant speed design and mechanical direct reading structure avoid electronic interference and ensure accurate and reliable measurement;
