Coating Viscosity Tester

Paint viscosity meters measure fluid viscosity by the resistance experienced by a rotor rotating in the paint. They are used to adjust dilution ratios on the production site and for laboratory quality control to ensure uniform coating flow. They are commonly employed in the production process control of paints and inks.
Selection
When selecting, consider the measurement range covering the viscosity range of the sample, the rotor material being resistant to solvent corrosion, the speed settings matching the shear rate requirements, digital readings being easier to read than analog ones, portable models being suitable for on-site rapid testing, and benchtop devices being suitable for precise laboratory measurements.
