The viscometer has the characteristics of high measurement sensitivity, reliable test results, convenient use and operation, and beautiful appearance. It is a precision instrument used to measure the viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids. It can be widely used in the measurement of the viscosity of various fluids such as grease, paint, plastic, medicine, food, paint, detergent, etc. The viscometer is driven by the motor through variable speed to rotate the rotor at a constant speed. When the rotor rotates in the liquid, the liquid produces a viscous moment acting on the rotor. The greater the viscosity of the liquid, the greater the viscous moment; conversely, the smaller the viscosity of the liquid, the smaller the viscous moment. The viscous moment acting on the rotor is detected by the sensor, and the viscosity of the measured liquid is obtained after computer processing.
The viscometer has high reliability and controllability. But in order to avoid some potential problems, some operating points are worth keeping in mind:
(A) The adaptability of the viscometer to the external environment is extremely small. Good instrument performance requires the elimination of all unnecessary friction that may affect the sensitivity of the instrument; good cleaning habits are required; and care needs to be taken to avoid dust, fumes, liquids, and other forms of contamination from entering the viscometer. If it is necessary to operate the instrument in a contaminated environment, we recommend the use of extended viscometer spindles or cleaning kits to reduce contamination from entering the system.
(B) Do not install a rotor with fluid attached to it.
(C) Do not expose the domestic Rotational Viscometer to an environment of 75°C. When it is necessary to measure the viscosity of samples at high temperature, it is recommended to use the extended spindle or the attached heating accessories.
(D) Avoid inserting and squeezing the rotor joint from the side or below, because the connecting screw can protect the center and bearing of the rotor, and such rough actions will damage or make the connecting screw insensitive. When accessing or removing a spindle, the viscometer always remembers to lift the spindle attachment screw slightly, not to knock the spindle into the sample well and not to pull directly on the spindle or spindle fitting.
(E) Do not drop the instrument or shake it violently. The base of the viscometer provides convenient and sturdy support. If you need to take the viscometer to other places for use, be sure to pack the viscometer for storage when not in use or during transportation.
