Frequently Asked Questions
How does a rotational viscometer work?
Rotational viscometers measure the resistance of fluid to torque or rotation. The viscometer’s rotor spins in the fluid, and the torque required to achieve a specific rotational speed indicates viscosity.
Can these viscometers handle high temperatures?
Both models are compatible with temperature sensors, ensuring accurate readings at varying temperatures, which is crucial for experiments involving thermal changes.
What is the primary difference between the YR05853 and YR05854 models?
The primary difference lies in the measuring range: YR05853 measures up to 100,000 mPa.s, while YR05854 can handle up to 2,000,000 mPa.s, making it suitable for more viscous samples.
Advantages and Disadvantages
The Kalstein rotational viscometers offer numerous advantages, including high precision, an intuitive UI via the 5-inch touch screen, and an automatic scanning feature that streamlines operations.
