Chemical Reagent ViscoMeter

Chemical reagent viscometers determine viscosity values by measuring the resistance of fluids in rotation or capillary tubes, and are used to monitor the flow characteristics of liquids such as coatings and inks, with applications in quality control and process adjustment.
Selection
When selecting, consider the viscosity range of the fluid being measured and match it with the instrument's measurement method; pay attention to temperature control accuracy to ensure data consistency; choose appropriate rotors or capillaries based on sample characteristics; factor in ease of operation and maintenance costs.
