Absolute viscoMeter

The absolute viscometer calculates viscosity by measuring the resistance generated when a fluid flows through a measurement system of known geometry. Its function lies in directly obtaining the absolute viscosity value of the fluid, making it suitable for research and development as well as quality control processes in industries such as coatings and inks.
Selection
When selecting a rotational viscometer, consider the viscosity range and rheological properties of the sample to match the instrument's measurement accuracy and rotational speed range. Assess the need for temperature control of the sample and ensure compatibility between the instrument's materials and the sample. Refer to the ease of operation and maintenance costs in practical application scenarios, and verify the instrument's suitability in accordance with industry standards.
