Viscometers are used to measure the viscous resistance of liquids and the absolute viscosity of liquids. They are widely used to measure the viscosity of oils, greases, paints, slurries, paints, foods, pharmaceuticals, and cosmetics. The instrument is equipped with 1-4 rotors, which can be selected according to the viscosity of the liquid to be measured.

1. Select the viscosity standard solution according to the measured viscosity range, and verify the instrument before each use of the viscometer or rheometer, or check it regularly to ensure the accuracy of the measurement. BROOKFIELD offers silicone oil or oil standards that meet Newtonian fluid properties for each viscosity range, with an accuracy of ±1%. The recommended viscosity of the viscosity standard is one year from the time it was opened.
2. When the rotor is placed in the sample, avoid air bubbles, otherwise the measured viscosity value will be reduced. The avoidance method is to tilt the rotor into the sample, and then install the rotor, the rotor can not touch the cup wall and the bottom of the cup. The sample being measured must not have a specified scale.
3, acid (PH) maximum can not exceed 2, if the acid is too large should use a special rotor, use the ULA to determine the sample size (only 16ml).
4. When measuring different samples, the rotor must be kept clean and dry. If the rotor has other samples or residual water after cleaning, it will affect the accuracy of the measurement.
5. When the value is relatively stable, otherwise the obtained value will have a large error.
6. When connecting the rotor, use your left hand to gently hold and pinch the mandrel (on the main machine) and rotate the rotor on the right hand. This operation is to protect the mandrel and the hairspring in the fuselage, which can extend the service life of the instrument.
7. When selecting the rotor, it depends on the viscosity of the sample being measured and the measuring range of the rotor number closest to the rotor.
8, the machine must be kept horizontal.
