Working principle of digital viscometer
Digital viscometers usually use the rotation method to measure viscosity. The instrument controls the rotation of the rotor through a stepper motor. When the rotor rotates in the liquid, it will be subject to the resistance of the liquid. By measuring the rotation speed and resistance of the rotor, the instrument can calculate the viscosity of the liquid and display it on the LCD screen.
Features of digital viscometers
High precision: The digital viscometer has high measurement accuracy and reproducibility, and can provide accurate viscosity data.
Multi-function: It has a variety of rotors and speed options, suitable for measuring liquids of different viscosities
Intelligent: Some models have data acquisition and program-controlled analysis functions, which can realize automatic operation and data recording
Temperature control: The built-in temperature probe can monitor the sample temperature in real time to ensure the accuracy of the measurement results
