The rotational viscometer is a digital viscometer, which is driven by the motor through a variable speed rotation at a constant speed. When the rotor rotates in the liquid, the liquid produces a viscosity moment acting on the rotor, and the viscous torque is also greater; conversely, the smaller the viscosity of the liquid, the smaller the viscous torque of the rotating viscometer. The viscous moment acting on the rotor is detected by the sensor and processed by the computer to obtain the viscosity of the measured liquid.
Using a rotary viscometer, the maximum acidity cannot exceed 2. If the acidity is too large, a special rotor should be used. When using the ULA, determine the sample volume (only 16ml). The upgraded small sample adapter can measure a minimum of 5ml. If the sample volume is minimal, Laminate should be considered. According to the measured viscosity range, the viscosity standard fluid is selected, and the instrument is verified before each use of the rotational viscometer, or periodically calibrated to ensure the accuracy of the measurement.
Rotary viscometer according to its design principle, there are several points of use it needs to pay attention to the use, the following to introduce you to the following: When connecting the rotor with the left hand gently lift and pinch the mandrel, right hand to rotate the rotor, this operation is In order to protect the mandrel and the hairspring in the body of the rotary viscometer, this can extend the life of the instrument.
