Overview
The NDJ-8S digital display Rotational Viscometer is an instrument that displays viscosity, Rotation speed, temperature, percentile torque, rotor number and the maximum viscosity value of the selected rotor at the current Rotation speed. The range is 20~ 2,000,000 mPa · s. Equipped with a small number of sample adapters, including one rotor of No. 21, 27, 28, and 29, the sample volume is only 10~ 20mL, which is suitable for expensive sample testing, and can be connected to the external circulation Thermostatic bath to control the temperature.
Features

2. Wide range, covering 20 to 2,000,000 mPa · s
3. Equipped with a small number of sample adapters, the sample volume is only 10~ 20mL, suitable for valuable sample testing
4. Can be connected to external circulation Thermostatic bath to control the temperature of the measured sample
5. Easy to disassemble and clean
6. Eight-speed Rotation speed control, providing 0.3/0 6/1.5/3/6/12/30/60rpm Rotation speed selection
7. reproducibility +/- 0.5% F.S, Measurement accuracy +/- 1% F.S
Principle
NDJ-8S digital display Rotational Viscometer rotates the swirl/spin rotor in the sample, measures the torque generated by the fluid resistance, and calculates the viscosity value in combination with the Rotor speed and specifications. The LCD screen displays parameters such as viscosity, Rotation speed, temperature, percentile torque, rotor number and the maximum viscosity value of the selected rotor at the current Rotation speed in real time.
Applications
Valuable sample testing, laboratory viscosity measurement
Steps
1. Select the appropriate rotor and install it
2. Prepare 10~ 20mL samples
3. Set the required Rotation speed (0.3/0 6/1.5/3/6/12/30/60rpm optional)
4. Start the measurement, observe the LCD display viscosity, Rotation speed, temperature, percentile torque, rotor number and the selected rotor at the current Rotation speed can measure the maximum viscosity value
5. Remove the rotor and clean it after measurement
Notice
• The sample volume is controlled within the range of 10~ 20mL
• Ensure that the rotor is properly installed and cleaned
• Dedicated Power Adapter (Input 100~ 240V 50~ 60Hz)
• Pay attention to temperature control during measurement, can be connected to Thermostatic bath
• Avoid exceeding the maximum viscosity value of the selected rotor at the current Rotation speed
