Overview
SHANGHAI JINGTIAN HBDV-1 digital display Rotational Viscometer is a wide range Rotational Viscometer with a measurement range of 640 to 320,000,000 mPa · s. The device uses digital display mode, and the LCD screen can display real-time information such as viscosity, shear rate, shear stress, Rotation speed, temperature, percentimeter torque, rotor number and the maximum viscosity value of the selected rotor at the current Rotation speed.
Features
1. Wide viscosity measurement range, covering 640~ 320,000,000 mPa · s.
2. Digital LCD screen, can display viscosity, Rotation speed, temperature, torque, rotor number and maximum measurable viscosity value and other parameters at the same time.
3. Equipped with a variety of rotor specifications (R2 #, R3 #, R4 #, R5 #, R6 #, R7 #) to adapt to different measurement needs.
4. Rotation speed can be continuously adjusted in the range of 0.1 to 99.9 rpm.
5. Measurement accuracy is high, +/- 1% F.S.; reproducibility is good, +/- 0.5% F.S.
Principle
The HBDV-1 digital display Rotational Viscometer works based on the principle of swirl/spin method. The instrument drives the selected rotor to swirl/spin in the sample at a set Rotation speed. When the rotor swirls/spins in the fluid, it will be subjected to Tack resistance and generate torque. The instrument calculates the viscosity value of the sample by measuring the torque value, combined with the rotor specification, Rotation speed and other parameters, and finally obtains the viscosity value of the sample, which is displayed on the LCD screen.
Applications
Petrochemicals, Paint inks, Food and Medicine, Cosmetics, Adhesives, Research and Education
Steps
1. According to the estimated sample viscosity range, select the appropriate rotor and install it on the instrument.
2. Place the sample in a suitable container and ensure that the rotor is immersed in the specified marking line position.
3. Turn on the power and set the required measurement Rotation speed through the instrument panel.
4. Start the measurement, after the display value is stable, read and record the viscosity value and Miscellaneous related parameters displayed on the LCD screen.
5. After the measurement is completed, turn off the power, remove the rotor and clean it.
Notice
• Please use the instrument-specific Power Adapter for power supply (input: 100~ 240V, 50~ 60Hz).
• When selecting the rotor and setting the Rotation speed, ensure that the Measured value is within the range of the instrument, and refer to the maximum measurable viscosity value displayed on the screen.
• Make sure the rotor is properly installed and immersed in the sample to the specified depth during measurement to ensure measurement accuracy.
• The instrument should be placed on a stable table to avoid vibration.
• The rotor should be cleaned in time after each use to prevent the sample residue from affecting the subsequent Measurement accuracy or damaging the rotor.
