Laminar Flow ViscoMeter

The laminar flow viscometer calculates fluid viscosity by measuring the pressure difference or flow rate as the fluid passes through a capillary under laminar flow conditions. It is used for viscosity testing of liquids such as coatings and inks to ensure that the flow properties of the products meet process requirements.
Selection
When selecting, consider matching the viscosity range of the fluid being measured with the instrument's measurement range, paying attention to temperature control accuracy and sample volume requirements. Prioritize measurement components made of corrosion-resistant materials, and verify calibration certificates and ease of operation.
