Measuring principle
The rolling and sliding movements of a ball through the sample liquid are timed in an inclined cylindrical measuring tube. The sample viscosity is correlated to the time a ball requires to traverse a definite distance. By turning the measuring tube upside down again the return of the ball may also be used for an additional measurement applying the return cons- tant. The test results are given as dynamic viscosity in the internationally standardized, absolute units of mPa·s.

FAQs of Hppler Viscometer:
Q: How does the Hppler Viscometer determine liquid viscosity using the falling ball principle?
A: This viscometer measures the time it takes for a high-precision glass ball to fall through a liquid inside a stainless steel tube. The rate of descent is influenced by the liquids viscosity, and that time is manually recorded and converted directly to viscosity readings using the analog scale.
Q: What is the recommended process for preparing a sample in the Hppler Viscometer?
A: To prepare a sample, fill the measuring tube with approximately 20 ml of the test liquid, select and insert a calibrated glass ball, and ensure the thermostat jacket is connected for controlled temperature. The sample should be measured when the temperature reaches stability within the desired range (+10C to +80C).
Q: When should the calibrated glass balls be chosen and how do they affect the measurement?
A: Calibrated balls are selected based on the expected viscosity of the sample. Using the provided set, choose the appropriate ball for the liquids viscosity range to ensure accurate and reliable measurement, as each balls density is precisely calibrated for specific ranges.
Q: Where is the Hppler Viscometer typically used, and for which substances?
A: The viscometer is routinely employed in laboratories across petrochemical, food, chemical, and pharmaceutical industries. It is suitable for measuring the viscosity of Newtonian liquids, such as oils, syrups, solvents, and pharmaceutical preparations.
Q: What benefits does the double-walled thermostat connection offer during measurements?
A: The double-walled jacket allows for connection to an external thermostat, providing constant temperature control. This feature is essential for ensuring the reproducibility and reliability of viscosity readings, especially for temperature-sensitive samples.
Q: How long does a typical viscosity measurement take using the Hppler Viscometer?
A: Most viscosity measurements are completed in less than one minute per sample. Manual recording allows for quick results, making the process suitable for routine testing and analytical applications requiring fast turnaround.
Q: What are the main advantages of using a manual Hppler Viscometer with an analog display?
A: Manual operation offers direct control over the measurement process, while the analog scale provides immediate and straightforward viscosity readings. This design reduces dependency on electronic systems and ensures high accuracy with minimal complexity.
