Three-tube viscoMeter

The three-tube viscometer determines the fluid viscosity by comparing the natural drainage times of the fluid in three glass tubes with different inner diameters. It is used for measuring the viscosity of fluids such as paints and inks. During operation, a constant temperature must be maintained, and the average drainage time of the three tubes should be recorded.
Selection
When selecting, consider the viscosity range of the fluid being measured. For conventional fluids, choose a measuring range of 1-10 centistokes. Pay attention to the cleanliness of the glass tube and the clarity of the scale. The ambient temperature fluctuation should be less than ±0.5℃. Ensure compatibility with the pipe diameter combinations specified by industry standards.
