Rotary Viscosity Meter Selects Viscosity Standard Solution Based On Viscosity Range

- May 20, 2018 -

1, the machine must be kept horizontal.

The

2. When the rotor is placed in the sample, it is necessary to 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.

The

3. When measuring different samples, the rotor must be kept clean and dry. If there are other samples remaining in the rotor of the rotating viscometer or the residual water after cleaning, the measurement accuracy will be affected.

The

4, the acidity (PH) can not exceed 2 maximum, if the acid is too large should be selected special rotor, use the ULA to determine the sample size (only 16ml).

The

5. When connecting the rotor, use your left hand to gently hold and pinch the spindle (on the main unit) 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.

The

6. When the value is relatively stable, otherwise the obtained value will have a large error.

The

7. When selecting the rotor of the rotating viscometer, it depends on the viscosity of the sample being measured and the measuring range of the No. 5 rotor to be the closest. Select the number.

The

8. Select the viscosity standard solution according to the measured viscosity range, and verify the instrument before using the viscometer or rheometer every time, or check it regularly to ensure the accuracy of the measurement.
