For systems that use a spring for measuring the torque, there are different models designed for different viscosity ranges. Results provide reasonable repeatabilty but the absolute precision is not reliable due to inadequate temperature precision.
Rotational Viscometer / infinite-gap geometry :: Anton Paar Wiki
A great number of standards is available for rotational viscometers, among them for example: Dynamic viscosity Learn more about the Rotational Principle. Rotational viscometers are the widest spread viscometers on the market and can be found in more or less all industries independent of company size. One spindle is suitable only for a part of the model’s measuring range.
Product Detail – ASTM-D2393-86
Temperature control Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control.
In addition, there are special sample adapters available for reducing the required sample volume, for extending the measuring range and for a wider adtm range. Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: Still, thermostat baths are available that can hold even a mL beaker.
The higher the tested viscosity ast, the stronger the spring has to be.
We offer typical values which are based on the values in brochures and standards but are not related to specific instruments. Standards and Norms A great number of standards is available for rotational viscometers, among them for example: Viscosity measuring range – for a model for medium viscosity materials, with several different spindles: Sample Typical sample volume for manual operation: Rotational viscometers are typically used for quality control.
Learn more about the Rotational Principle. Tests are performed at ambient temperature.
Rotational viscometers cover a very wide measuring range. The resulting wide gap between the bob and the vessel’s wall is assumed to be infinite.
Performance Rotational viscometers cover a very wide measuring range. Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control.
