Precision-Engineered Spindles for Accurate Viscosity Measurement
The performance and accuracy of a viscometer depend significantly on the type of spindle used. Torontech offers a complete range of viscometer spindles compatible with the ToronVisc™ series, including LV, RV, HA, HB, CAP, and SC4 spindles. These spindles cover a broad viscosity range from low-viscosity fluids like water and oils to high-viscosity substances such as adhesives, creams, and resins.
Whether you're measuring Newtonian or non-Newtonian fluids, in industrial or lab environments, selecting the correct spindle ensures maximum accuracy, repeatability, and compliance with international testing standards.
