Various kinds of electronic viscosity testers are known. Some rely on rotating spindles and others use vibrating tubes. The spindle type rotates in the liquid, and the power it requires to do so aids in gauging viscosity. The vibrating tube type works by sensing how the liquid affects the vibration of the tube. ZONWON’s Viscometers is minimalist for workers’ convenient of use. It frequently shows results on a screen, so workers can see the viscosity immediately. This is useful for rapid decision-making in a busy factory or lab.
