Outflow ViscoMeter

An outflow viscometer calculates viscosity by measuring the time required for a fixed volume of liquid to flow out through a standard aperture. Based on gravity-driven flow, the time is proportional to the viscosity. It is used for rapid testing of Newtonian fluids such as paints and inks, offering simple operation but limited precision.
Selection
When selecting, consider matching the viscosity range of the material being tested with the instrument's measurement range, and prioritize standard aperture specifications. Pay attention to temperature control capabilities and verify the validity of calibration certificates. Choose stainless steel or plastic materials based on the corrosiveness of the material; for routine quality inspection, opt for the more affordable glass capillary models.
