Different Types or Models of Viscometers
Kalstein offers a wide range of viscometers designed to meet various needs in polymer research. Among the most common models are:
- Rotational viscometers: These models are ideal for measuring the viscosity of non-Newtonian fluids, whose viscosity changes under different flow conditions. They are widely used in polymer research due to their ability to provide detailed measurements under varying applied forces.
- Capillary viscometers: Ideal for Newtonian liquids, where viscosity is constant under any flow condition. These viscometers are simpler and are often used in applications where the liquids being measured exhibit constant viscous behavior.
- Falling ball viscometers: Used to measure the viscosity of liquids by observing the fall speed of a sphere. These viscometers are less common in polymer research but useful in specific cases.
- Digital viscometers: Incorporating state-of-the-art technology, these models allow for greater automation in measurement and facilitate data processing and storage through integrated software.
Each model offers unique advantages depending on the type of liquid being analyzed, and selecting the right viscometer is crucial for obtaining accurate and reliable results.
Why Are These Viscometers Priced This Way?
The price of Kalstein’s viscometers is directly related to the quality of their components and the advanced technology they incorporate.
