Air ViscoMeter

An air viscometer calculates viscosity by measuring the time difference for gas to flow through a capillary tube, utilizing Poiseuille's law to establish the relationship between flow time and viscosity. It is used to detect the viscosity of solvent gases in coatings and inks, monitor gas flow characteristics during production, and is applied in quality control in industries such as printing and plastics.
Selection
When selecting, consider that the measurement range covers the viscosity of the gas to be tested, the temperature control accuracy meets the experimental conditions, and the capillary size is compatible with the sample characteristics. Pay attention to the corrosion resistance of the instrument materials, the simplicity of the operation interface, and the compatibility of the data output format with the existing system. Include the availability of calibration services and maintenance costs in the evaluation.
