British Standard Flow Cup

The BS flow cup measures viscosity by timing how long it takes for the paint to flow completely through a small hole at the bottom of the cup. It is used in industries such as coatings and inks for on-site, rapid testing of fluid flowability, offering simple operation and intuitive results.
Selection
When selecting a BS flow cup, it is necessary to match the viscosity range of the material being tested, consider the aperture size of the cup mouth, verify the accuracy of the standard scale, inspect the corrosion resistance of the stainless steel material, and select the corresponding model based on commonly used ASTM or ISO standards.
