STM-2T Krebs Stormer Viscometer
Optimize your testing process with the STM-2T Krebs Stormer Viscometer, specifically engineered for Paints, Coatings, and Inks.
- Maximum Range Up to 141.0KU
- Accuracy: ±1%
- Repeatability: ±0.5%

Technical Specifications
*The cP values are derived through conversion from KU measurements in accordance with ASTM D562 standard. Due to the specific nature of this conversion methodology, these cP readings should be treated as reference values only. Direct comparison with cP measurements from other rotational viscometers (such as LV/RV series) is not recommended, as the conversion algorithms and measurement principles may differ significantly. For cross-instrument validation, please use the primary KU measurements.
