Three-tube viscosity measurement apparatus

The three-tube viscometer measures the time it takes for a liquid to flow through three glass tubes of different inner diameters under the influence of gravity, and then converts this time into viscosity. It is used for detecting the viscosity of fluids such as coatings and inks, enabling control over production processes and product quality.
Selection
When selecting, consider that the measurement range matches the sample viscosity, the glass tube material is corrosion-resistant, the temperature control accuracy meets requirements, the ease of operation aligns with usage habits, and the equipment is stable with easy maintenance.
