How They Work
The Viscosity Measuring Analyzer from Kalstein operates by utilizing a digital mechanism that ensures precision and ease of use. It measures the resistance of a fluid to gradual deformation by shear stress. This is achieved through its wide range of spindle speeds, which allows for comprehensive analysis across various viscosities.
The RIGOL NDJ-5S employs a rotational method where the spindle rotates in the sample fluid, and the resistance encountered provides the viscosity reading. Although effective, it is more suited to less complex applications due to its limited measurement range and lack of digital enhancements.
