Stormer Rotary ViscoMeter

The Stormer viscometer measures viscosity by rotating a paddle in the sample and determining the torque required to maintain a fixed rotational speed, which is then converted into a viscosity value. It is used for testing the viscosity of fluids such as paints and inks to ensure that the flow properties meet requirements during application or printing.
Selection
When selecting, consider matching the sample viscosity range with the instrument's measurement range, and ensure the paddle specifications correspond to the sample characteristics. Pay attention to temperature control requirements, and ensure the calibration method is simple and reliable. Configure interface functions according to data recording needs, and select materials that are resistant to corrosion from the sample.

Stormer Viscometer for Determining Krebs Viscosity of Paints
This article introduces the method of measuring the Krebs viscosity value of colored paints using a Stormer viscometer. Viscosity is a key indicator that affects the application and storage of coatings. The Krebs unit (KU) quantifies viscosity based on the resistance encountered by a rotor as it rotates within the paint sample.
Stormer viscometer measures the KU viscosity of latex paint
This article introduces the method of measuring the KU viscosity of latex paint using a Stormer viscometer. The viscometer measures the load required to maintain a fixed rotational speed through the rotation of its paddle, thereby calculating the KU value, which is related to the application and storage properties of the coating.
Rotational Viscometer vs. Stormer Viscometer: How to Choose the Right Instrument Based on Coating Type
The rotational viscometer measures viscosity by detecting rotor torque and can analyze rheological properties at different shear rates, making it suitable for research and precise measurements. The Stormer viscometer uses the load at a fixed rotational speed to determine the KU value, simulating construction conditions, and is commonly used for rapid on-site evaluation of coating application performance.
