Product description:This viscometer is a machine to measure the viscosity of newton liquid. The liquid should have good fluidity or the reading result will not be such accurate. As a digital viscometer, it is mainly controlled by micro computer, which features with accurate reading and stable work. 4 rotors included will help you measure various viscosity of different liquids. After use, you can put the part in the the metal box. It will help you keep the parts in order and carry it everywhere. Note: 1. No. 0 rotor is an optional accessory to measure the low viscosity samples than 20 mPa.s. The sample volume only needs 25ml. 2. Many of the suspensions, emulsions, polymers and other viscosity liquids are "non-Newtonian liquids". The apparent viscosity changes with the shearing speed and time, so it is normal that the results is inconsistent under different rotors, rotating speed and time. Generally, for non-Newtonian liquids, the rotor, speed and time should be specified. 3.We offer ONE-YEAR warranty and lifetime technical support. If you need, please contact us by email.
