Dial-type Rotational Viscometer

A dial rotation viscometer operates by using a motor to rotate a rotor within the sample, measuring the viscous resistance encountered by the rotor and converting it into a pointer reading. It is used for rapid on-site viscosity testing of fluids such as coatings and inks, offering simple operation and portability.
Selection
When selecting, consider the viscosity range of the sample and ensure it matches the instrument's measurement range. The rotor model must be suitable for the characteristics of the material being tested. Pay attention to temperature adaptability and calibration methods. Pointer readings should meet the required detection accuracy. Prioritize robust and durable mechanical structures.
