Stormer Viscosity Tester

The Stormer viscometer measures the torque required to maintain a fixed rotational speed of a rotor immersed in a sample, converting it into Krebs unit viscosity values. It is used for quality control of fluids such as paints and inks, ensuring that their application leveling properties and storage stability meet conventional requirements.
Selection
When selecting, consider matching the sample viscosity range with the instrument's measurement range, and ensure compliance with the ASTM D562 standard method. The rotor material must be resistant to sample corrosion, and the temperature control function should be suitable for the laboratory environment. The data output interface should be compatible with existing recording methods, and operational training should be provided to ensure basic usage proficiency.
