Overview
Shanghai JINGTIAN SNB-2 digital display Rotational Viscometer is a precision measuring instrument with a range of 12 to 6,000,000 mPa · s. Equipped with data analytics software, it can automatically collect, record measurement data and generate relevant Linear dispersion, support historical data comparison and chart output.
Features
1. The LCD screen displays comprehensive information, including viscosity, shear rate, shear stress, speed, temperature, percentile torque, rotor number and the maximum viscosity value that can be measured under current conditions.
2. Measurement accuracy is high, reproducibility is +/- 0.5% F.S, Measurement accuracy is +/- 1% F.S.
3. Equipped with special data collection analysis and drawing software, support automatic recording, data analytics, ten historical data comparison and output Excel format files and print charts.
4. Adopt continuously variable speed mode, with a speed adjustment range of 0.1 to 99.9 rpm, providing flexible operation.
5. Provide a variety of rotor specifications (L1 #, L2 #, L3 #, L4 #) to adapt to different viscosity measurement needs.
Principle
The Viscometer works on the principle of swirl/spin viscosity measurement. The motor drives the rotor at a uniform speed swirl/spin in the sample, and the Tack resistance to the rotor forms torque. The instrument measures this torque value, combines the rotor specification and speed, and calculates the viscosity value of the sample through internal calculation, and synchronously calculates the relevant parameters such as shear rate and shear stress.
Applications
Chemical, Petroleum, Food, Pharmaceutical, Coatings, Adhesives, Cosmetics, Research and Education
Standards
The product information does not mention specific compliance standards.
Steps
1. Connect the power adapter and turn it on.
2. Select the appropriate rotor according to the estimated viscosity value and install it.
3. Immerse the rotor into the sample to be tested to the specified marking line.
4. Set the required speed through the instrument panel or software.
5. Start the measurement, and record or automatically collect the data through the software after the reading is stable.
6. After the measurement is completed, clean the rotor and shut down.
Notice
Before use, make sure that the input voltage of the power adapter matches the local power grid (input 100~ 240V, 50~ 60Hz).
• When selecting a rotor, ensure that the estimated sample viscosity is within the measurable range of the rotor and rotational speed combination.
• Be careful when immersing the rotor to avoid touching the wall or bottom of the container, so as not to affect the Measurement accuracy.
• When measuring different samples, be sure to clean the rotor thoroughly to prevent cross-contamination.
• When not in use for a long time, please keep the instrument and accessories properly.
