Overview
The LICHEN NDJ-5T Touch Screen Viscometer is a Physical PropertyAnalysis instrument for the measurement of fluid viscosity. Viscosity is a physical property that reflects the internal friction of a fluid and is closely related to the chemical composition of a substance. The instrument monitors the composition or quality of a substance by measuring viscosity. It is suitable for industrial production and scientific research.

2. With data storage function, 30 measurement results can be stored.
3. With Linear dispersion function, it can display and view the measurement Linear dispersion.
4. LCD color touch screen, intuitive display, easy to operate, beautiful appearance.
5. Equipped with RS232 interface and Bluetooth printing function, it can be connected to the printer output.
6. Equipped with temperature sensor interface, can detect sample temperature in real time.
7. Equipped with a computer interface, it is convenient to connect and output with the computer.
8. With timing measurement function and over-range alarm function.
9. Microcomputer control technology, high measurement Sensitivity, reliable test results, good anti-interference.
10. A universal joint is added at the interface where the rotor is connected to facilitate steering.
11. The handwheel is made of high-wear-resistant, high-performance engineering plastics, making it easy to operate.
12. Support Chinese and English display, can be switched randomly.
13. Can be used to measure the absolute viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids.
Principle
The Viscometer determines the viscosity of a fluid by measuring the internal friction that occurs between molecules when it is subjected to an external force. The instrument calculates the viscosity of the fluid by driving the rotor to swirl/spin in the fluid and measuring the torque required to maintain a specific speed.
Applications
Industrial production, scientific research
Steps
1. Select the appropriate rotor according to the estimated sample viscosity and install it.
2. Place the sample in the measurement vessel, ensuring that the rotor is immersed in the sample to the specified depth.
3. Set measurement parameters such as rotational speed through the touch screen.
4. Start the measurement, the instrument will automatically run and display the viscosity value.
5. After the measurement is completed, the data can be viewed, stored or output through the interface.
Notice
• Please select the appropriate rotor according to the estimated viscosity range to ensure the Measurement accuracy.
• Ensure that the rotor is properly installed and immersed in the sample to the specified depth.
• Before measurement, the sample should be in a stable state without obvious bubbles or impurities.
• The instrument should be used under the conditions of environment Operating temperature 5~ 35 ℃ and relative humidity ≤ 80%.
• Power supply voltage specified (AC110-240V 50/60Hz or DC12V).
• Avoid using instruments in environments with strong electromagnetic interference.
• Regularly clean and maintain rotors and measurement components.
• Conduct override alarm function test to ensure its normal operation.
