Coating and Paint Viscosity Tester

The paint viscosity tester determines viscosity by measuring the fluid's resistance to flow under specific conditions. Its principle is based on rotational or efflux measurement methods, where the instrument drives a rotor to rotate in the sample or records the time it takes for the fluid to pass through a standard aperture. This equipment is used in production sites and laboratories to monitor the application performance and storage stability of coatings, ensuring consistency across product batches.
Selection
When selecting a paint viscosity tester, ensure it matches the viscosity range of the material being tested, considering whether the fluid is Newtonian or non-Newtonian. Choose a portable or benchtop structure based on the usage scenario, and confirm that the measurement accuracy meets process requirements. Verify compliance with standard specifications and evaluate the ease of cleaning and maintenance. Pay attention to the temperature control function and its compatibility with the sample volume.
