Relative Viscosity Tester

The relative viscometer reflects the internal resistance of a fluid by measuring the ratio of the flow time of the fluid in a capillary tube to that of a standard liquid. This instrument is used for viscosity monitoring in industries such as coatings and inks to ensure that the flow performance of products meets process requirements.
Selection
When selecting, it is necessary to match the viscosity range of the sample, confirm the temperature control accuracy, consider the corrosion resistance of the material, verify the measurement repeatability error, combine ease of operation and data output methods, and adapt to the actual application scenario.
