Overview
The NIRUN NDJ-5S digital Viscometer is an experimental instrument for the measurement of viscosity of liquid or semi-solid substances. It uses a swirl/spin cylindrical rotor in the object to be measured to measure viscosity according to the resistance between the rotor and the substance. It is widely used in chemical, food and other industries to determine the flowability of substances, quality control and viscosity changes during product development.
Features
1. Using an improved 16-bit microcomputer processor as the core, the anti-interference performance is greatly improved
2. 4-line digital display with digital LCD with blue backlight function
3. Stepper motor direct drive, no gear, accurate speed
4. Standard RTD temperature probe and RS232 interface
5. Display the maximum viscosity value of the rotor that can be measured at the current speed
6. With measurement timing function, printing time interval setting and viscosity unit selection
7. The viscosity value shows continuous change
8. Measurement range beyond the alarm sound prompt
9. Computer full-scale linear correction
10. AC power adapter 100V-240V, good anti-interference
Principle
The rotational viscometer swirls/spins a cylindrical rotor or disc in the object to be measured to measure viscosity based on the resistance between the rotor and the liquid or semi-solid. The rotational speed of the rotor and the applied force have an impact on the viscosity measurement results.
Applications
Inks, Inks, Glues, Latex, Solvent Adhesives, Biochemical Agents, Polymer Solutions, Petroleum, Paints Coatings, Solvents, Lithium Battery Paddles, Cosmetics, Milk Products, Products, Juices, Petroleum, Solvents
Steps
1. Select the appropriate rotor specification (1 #, 2 #, 3 #, 4 #or 0 #optional)
2. Set Rotor speed (6/12/30/60rpm)
3. Connect RTD temperature probe for temperature measurement
4. Start the measurement and observe the viscosity change on the LCD screen
5. If the Measurement range is exceeded, the device will issue an alarm sound
6. Connect computer via RS232 interface for data collection and processing
Notice
• Power supply voltage within AC 100-240V range before use
• Select the appropriate rotor size and speed to ensure Measurement accuracy
Measurement range beyond the device will sound alarm, please adjust the measurement parameters in time
Periodic equipment calibration to ensure measurement accuracy
• Optional special viscosity measurement thermostatic sink, ultra-low viscosity adapter, micro printer and Glass circulation cup and other accessories to expand the function
