YUEPING NDJ-1 Rotational Viscometer measurement of grease, paints, plastics, food, Adhesives, cosmetics, etc

Yueping NDJ-1 Rotational Viscometer is a pointer-type Rotational Viscometer with a measuring range of 1 to 1× ¹⁰⁵ mPa.s. The measured viscosity value can be read directly from the pointer disk. It is suitable for grease, paint, plastic, Food, medicine, adhesives, cosmetics and other industries to test the viscosity of liquids. NDJ-1 Rotational Viscometer has high measurement accuracy, which is ±5% Newtonian liquid. NDJ-1 Rotational Viscometer is equipped with No. 1, 2, 3 and 4 rotors, and No. 0 rotor needs to be purchased separately according to user needs.

Rotary viscometer operation method

1) Prepare the liquid to be tested, place it in a beaker or a straight container with a diameter of not less than 70mm, and accurately control the temperature of the liquid to be tested.

2) Install the protective frame on the Yueping NDJ-1 Rotational Viscometer (screw right to install it, turn left to remove it).

3) Screw the selected rotor into the connecting screw (screw to the left to install it, and turn to the right to remove it). Rotate the lifting knob to lower the NDJ-1 Rotational Viscometer slowly, and gradually immerse the rotor into the measured liquid until the rotor liquid level mark is parallel to the liquid level. Adjust the level of the NDJ-1 rotary viscometer , turn on the motor switch, turn the speed change knob to make the required speed up, align with the speed indication point, and the rotor rotates in the liquid. After several rotations, generally (20-30) s, or according to the specified time, the pointer can be read when it becomes stable. Press the pointer control lever to fix the reading, and turn off the motor when the pointer turns to the reading window (Note: 1. Do not use too much force. 2. When the speed is slow, you can read directly without using the control lever), and the pointer stops at the reading at this time In the window, the measurement data can be obtained. If the pointer is not in the reading window after the motor is turned off, you can continue to press the pointer control lever to turn on and off the motor repeatedly. After several exercises, you can master it proficiently, make the pointer stop in the reading window, and read the data.

4) When the value pointed by the pointer is too high or too low, the rotor and the speed can be changed, and the reading must be between 30-90 on the scale.

Features

Viscometer NDJ-1 is widely used to measure the viscous resistance and absolute viscosity of various fluids such as grease, paint, plastic, food, medicine, adhesive, cosmetics, etc. When using, it is necessary to install and measure according to the requirements of the manual.

Q/YXLQ1

How to operate the viscometer NDJ-1 to measure more accurate values?

1. Accurately control the temperature of the measured liquid.

2. Immerse the rotor in the liquid to be measured for a long enough time and keep the temperature constant so that it can be consistent with the temperature of the liquid to be measured.

3. Ensure the uniformity of the liquid.

4. Place the rotor in the center of the container as much as possible during the measurement.

5. Prevent air bubbles from adhering to the bottom of the rotor when the rotor is immersed in liquid.

6. Change the rotor or speed to make the reading on the dial higher.

g. Assay using a protected frame.

7. Keep the rotor clean.

8. If the power frequency is not accurate, correct it according to the correction formula.

9. Operate strictly in accordance with the operating rules.
