The LBN-II Falling Rod Viscometer is used to determine the apparent viscosity of non-Newtonian fluids, such as inks, at a specific temperature and a shear rate of 2500 s?1. It can also calculate the apparent yield value and shortness of the tested sample. Main technical parameters: 1. Diameter of the falling rod and guide sleeve: φ12 mm 2. Falling height: 100 mm 3. Measurable viscosity range: 1–300 Pa·s (non-Newtonian fluids) 4. Timing accuracy: 0.01 s 5. Weight of counterweights: 25–2000 g 6. Instrument weight: 15 kg
