Overview
NDJ-5S liquid crystal rotational viscometer is an upgraded product of CNSHP brand rotational viscometer. It adopts professional mechanical design, manufacturing process and microcomputer control technology. The data collection is correct, and it is equipped with a blue backlit high-luminance LED display screen for clear display. The instrument has the characteristics of high measurement Sensitivity, reliable test results, convenient operation, and beautiful appearance. It is suitable for the measurement of absolute viscosity of Newtonian liquids and apparent viscosity of non-Newtonian liquids. It is widely used in the measurement of viscosity of various fluids such as grease, paints, plastics, food, Coatings, detergents, etc. The instrument is also equipped with RS-232, temperature sensor, printer and other interface functions, and can be equipped with PC cable, temperature sensor and micro printer to expand the function.
Features
1. All aluminum head, Shielding performance is superior;
2. High luminance LCD display;
3. Equipped with RS-232 Communication interface to connect to PC;
4. Optional temperature sensor, can measure the liquid temperature;
5. Optional micro printer can directly print test results;
6. Automatic scanning function, can automatically select the appropriate rotor number and Rotation speed;
7. Single measurement automatically stops, and the rotor automatically stops after the measurement result is stable;
8. Operating language support Chinese/English.
Principle
Based on the rotational viscometer principle, this instrument drives the rotor to swirl/spin in the liquid through microcomputer control technology to measure the absolute viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids. The data collection is correct and the results are displayed in combination with a high luminance LED display.
Applications
Grease, paints, plastics, food, Coatings, detergents
Steps
1. Connect the power supply, ensure that the voltage is AC 220V +/- 10%, Frequency 50Hz +/- 10%;
2. Choose suitable rotors as needed (1 #, 2 #, 3 #, 4 #, 0 #optional);
3. Turn on the instrument, select Rotor speed (6/12/30/60rpm) or use the automatic scanning function;
4. Immerse the rotor in the liquid to be tested and start the measurement;
5. The instrument automatically measures and stops the rotor after the result is stable, displaying the viscosity value;
6. Optional connection to PC, temperature sensor or micro printer for data recording, temperature measurement or printing results.
Notice
• Operating temperature in the range of 5~ 35 ℃;
• relative humidity not exceeding 80%;
• Power supply voltage check before use is AC 220V +/- 10%;
• Correct selection of rotor and Rotation speed to avoid measurement errors;
• Regularly calibrate instruments to ensure Measurement accuracy;
• Avoid use in humid or corrosive environments;
• Optional functions require additional installation of corresponding accessories and software.
