What Is a Rotational Viscometer?<\/h2>\n

The Rotational Viscometer<\/strong> measures the resistance of a liquid against the movement of a rotating spindle. As the spindle rotates inside the sample, the liquid produces mechanical resistance. The instrument converts this torque into a viscosity value.<\/p>\n

Viscosity directly affects the processing and application behaviour of many materials. Therefore, laboratories use rotational viscometers for oils, chemicals, polymers and bituminous binders. ASTM D2196<\/strong> covers rotational viscosity measurements for various non-Newtonian materials.<\/p>\n

Wide Viscosity Measuring Range<\/h2>\n

The instrument provides a broad measuring range from 10 to 2,000,000 cP (mPa\u00b7s)<\/strong>. This allows laboratories to test both relatively low-viscosity and highly viscous materials with the same system.<\/p>\n

Measurement accuracy of approximately \u00b11.0%<\/strong> supports routine quality control and research applications. The operator selects an appropriate spindle and rotational speed according to the characteristics of the sample.<\/p>\n

Measurements at different speeds can also provide useful information about the behaviour of non-Newtonian materials.<\/p>\n

Integrated Temperature Monitoring<\/h2>\n

An immersion-type temperature sensor continuously monitors the sample during testing. The system provides temperature measurements from 0 to 100 \u00b0C<\/strong>.<\/p>\n

Temperature is particularly important because viscosity can change significantly as a material heats or cools. For this reason, comparative measurements should be performed under consistent thermal conditions.<\/p>\n

For bituminous binders, rotational viscosity helps laboratories evaluate handling, pumping, mixing and application characteristics.<\/p>\n

Automatic Measurement and Data Transfer<\/h2>\n

The integrated timer allows the instrument to operate independently for a user-defined measurement period. This helps laboratories apply consistent test durations to different specimens.<\/p>\n

An RS232 communication interface<\/strong> allows measurement data to be transferred to a computer. Compatible software can display viscosity and temperature profiles in graphical and tabular formats. An optional printer can also be connected for direct result output.<\/p>\n

Stable and Accurate Installation<\/h2>\n

The instrument includes adjustable feet and an integrated spirit level. These features help keep the measuring spindle correctly aligned with the sample.<\/p>\n

Proper alignment is important for repeatable measurements. The adjustable structure also makes it easier to work with different laboratory containers and sample heights.<\/p>\n

Bitumen and Binder Viscosity Testing<\/h2>\n

The Rotational Viscometer<\/strong> supports laboratory procedures according to ASTM D4402\/D4402M, EN 13302 and AASHTO T316<\/strong> for bituminous binders. ASTM D4402\/D4402M focuses on the apparent viscosity of asphalt binders at elevated temperatures, while EN 13302 covers dynamic viscosity measurement using a rotating spindle device.<\/p>\n

Overall, the LT-AS1000 Rotational Viscometer<\/strong> combines a wide measuring range, temperature monitoring and digital data management. Therefore, laboratories can evaluate the viscosity of different liquids accurately and repeatably.<\/p>\n
