Overview
The NIRUN NDJ-8S Digital Viscometer is a precision measuring instrument with stepper motor direct drive technology, equipped with a No. 0 rotor, suitable for a wide range of viscosity measurements from low to high. It is designed for accuracy and Stability, with rich display and prompt functions.
Features
1. Adopt stepper motor direct drive, gearless structure to ensure accurate speed.
2. LCD LCD screen with blue backlight, large amount of information display.
3. The maximum viscosity value that can be measured by the rotor at the current speed can be displayed.
4. With measurement timing function.
5. The viscosity value shows continuous change.
6. Measurement range exceeds the alarm sound prompt.
7. After full-scale linear correction by computer.
8. Adopt 100V-240V AC power adapter for good anti-interference performance.
Principle
The Viscometer works on the principle of swirl/spin viscosity measurement. The instrument drives the rotor at a constant speed swirl/spin in the sample, and the rotor is subjected to torque formed by the sample Tack resistance. The viscosity value of the sample can be accurately calculated by measuring the torque required to maintain the uniform swirl/spin of the rotor and processing it with a microcomputer control system.
Applications
Inks, Glue, Latex, Solvent Adhesive, Polymer Solution, Petroleum, paints Coatings, solvents, cosmetics, milk products, products, juices
Steps
1. Choose the appropriate rotor and speed according to the estimated viscosity.
2. Immerse the rotor into the sample to be tested to the designated marking line.
3. Turn on the instrument power and set the required speed.
4. Start the measurement and wait for the reading to stabilize or reach the set time.
5. Read viscosity measurements from the display.
6. After the measurement is completed, turn off the power and clean the rotor.
Notice
• Please ensure that the instrument is placed horizontally before use.
• Select the appropriate rotor and rotational speed combination according to the sample viscosity range to avoid exceeding the Measurement range.
• Avoid bubbles when immersing in the rotor and ensure that the immersion depth meets the requirements.
• When measuring different samples, be sure to clean the rotor thoroughly to prevent cross-contamination.
• If the measurement value exceeds the current range, the instrument will issue an alarm prompt, and the rotor should be replaced or the speed should be re-measured.
• When not in use for a long time, please disconnect the power supply and store the instrument and rotor properly.
