YUEPING NDJ-4 Rotational Viscometer for measurement of oils, paints, food, gluing agents, cosmetics, etc

Yueping NDJ-4 Rotational Viscometer is designed according to Q/YXLQ1 standard, the measurement range is 10～2×10 6 ^mpa.s , and the measurement error is ±5% (Newtonian liquid). NDJ-4 Rotational Viscometer is a Dial-Type Rotational Viscometer, which uses an 8-speed stepping motor, which can provide a variety of rotational speeds to meet different viscosity measurement ranges. Using universal rotating shaft, the operation is simple and convenient, and the measurement is stable. The NDJ-4 Rotational Viscometer is equipped with a variety of spindles.

use

NDJ-4 rotary viscometer can measure the viscous resistance and dynamic viscosity of liquid in a large range. It can be widely used in the viscosity determination of various fluids such as oil, paint, plastic, food, medicine, and viscometer.

Instructions

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 NDJ-4 Rotational Viscometer (screw right to install it, and turn left to remove it).

3. Screw the selected rotor into the connecting screw (rotate to the left to install, and rotate to the right to remove).

4. Rotate the lifting button to make the NDJ-4 rotary viscometer descend slowly, and the rotor is gradually immersed in the liquid to be measured until the rotor liquid level mark is parallel to the liquid surface.

5. Adjust the level of the NDJ-4 rotary viscometer, turn on the motor switch, turn the speed change knob to make the required speed number upward, 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.

6. 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), at this time, the pointer stops in the reading window, and 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.

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

equipment structure

Precautions

1. This instrument is suitable for use in normal temperature environment.

2. The instrument needs to be measured within the specified frequency and Voltage tolerance range, otherwise the measurement accuracy will be affected.

3. Try to use the bracket to fix the instrument and use it. If you are holding the instrument, you should keep the instrument stable and level.

4. Care should be taken when loading and unloading the rotor. During the assembly and disassembly, the connecting screw should be lifted slightly for operation. Do not use too much force, and do not apply lateral force to the rotor to prevent the rotor from bending.

5. Do not place the instrument on its side or upside down after installing the rotor.

6. Be sure to change the speed while the motor is running.
