In the realm of laboratory instrumentation, precision and versatility are paramount. The viscosity measuring analyzers, models YR05855 and YR05856, by Kalstein, epitomize this standard. These state-of-the-art viscometers are engineered to provide accurate and reliable measurements, making them indispensable tools for researchers who require precision in their fluid dynamics analyses.
Description of the Product
The Kalstein viscometers are equipped with multiple rotating speed settings, allowing for flexibility in measurement and adaptability to a wide range of fluid viscosities. Specifically, model YR05855 offers rotating speeds of 3, 6, 12, 30, and 60 r/min, while YR05856 extends this range with additional speeds of 0.3, 0.6, 1.5, 3, 6, 12, 30, and 60 r/min. This range enables precise adjustments tailored to specific fluid types and measurement requirements.
Among the standout specifications is the impressive measuring range. Model YR05855 measures viscosities from 1 to 100,000 mPa.s, whereas model YR05856 significantly expands this with a range of 1 to 6,000,000 mPa.s. This makes the latter particularly suitable for a broader spectrum of industrial and research applications where higher viscosities are encountered. Both models accommodate standard rotors 1-4#, with an optional 0# rotor available for viscosities lower than 10 mPa.s.

Frequently Asked Questions
What is the primary difference between models YR05855 and YR05856?
While both models are designed for precise viscosity measurement, the YR05856 offers a wider range of viscometry and lower starting rotating speeds, making it suitable for a broader range of fluid viscosities.
Are additional rotors necessary for low viscosity measurements?
Yes, for measurements lower than 10 mPa.s, the optional 0# rotor is recommended to achieve precise results.
Is there a calibration service available?
Kalstein offers support for calibration to ensure the sustained accuracy and reliability of your viscometer over time.
Advantages and Disadvantages
The viscometers from Kalstein offer notable advantages, including a broad measurement range, high accuracy with a measuring error as low as ±0.5% for model YR05855, and a robust suite of rotor options. However, the extended measuring capabilities of model YR05856 are complemented by a slightly higher measuring error rate, and the need for specific rotor adjustments for ultra-low viscosity fluids might pose additional complexity for some users.
Field Applications
In real-world settings, the Kalstein viscometers are employed across various industries, including pharmaceuticals, food processing, and petrochemicals, offering critical insights into the fluid dynamics of materials. Their sophisticated timer functions and adjustable speed allow for detailed observation of viscosity changes over time under different conditions.
