Constant Temperature Bath ViscoMeter

The constant temperature bath viscometer maintains the sample at a constant temperature through a heating bath. When the rotor rotates in the sample, it experiences viscous resistance, and this resistance is measured and converted into a viscosity value. It is used to detect the viscosity of fluids such as coatings and inks at specific temperatures, ensuring process stability.
Selection
When selecting, consider that the measurement range covers the viscosity of the sample, the temperature control accuracy matches the requirements, the rotor material has corrosion resistance, the sample volume fits the cell capacity, the operation interface aligns with usage habits, and the data output method meets recording needs.
