Overview
The SNB-1T digital rotational viscometer is a modern viscosity measurement instrument integrated with touch screen technology. It uses a 5-inch large color touch screen for easy and intuitive operation. It can quickly and accurately determine the absolute viscosity of Newtonian liquids or the apparent viscosity of non-Newtonian liquids. The instrument has a built-in Linux system, powerful functions, supports self-built 30 sets of test procedures, and has the advantages of multiple measurement parameters, high accuracy, stable speed, and strong anti-interference. It can meet a variety of viscosity measurement needs.

5. Front level, level adjustment is intuitive and convenient.
6. Optional temperature probe, constant temperature bath, thermostatic cup, printer, standard viscosity sample and other accessories.
7. Support Chinese and English operating systems.
Principle
SNB-1T digital rotational viscometer drives the rotor to swirl/spin at a constant speed in the liquid to be measured by the motor. When the rotor swirls/spins, it is subject to the viscous resistance of the liquid, which is proportional to the viscosity of the liquid. The instrument measures the resistance and calculates it internally, and finally displays the viscosity value of the liquid and related parameters on the screen.
Applications
Paints, Coatings, Cosmetics, inks, Pulp, Food, Oil, Starch, Solvent Adhesive, Latex, Biochemical, Asphalt, Paraffin, Hot-melt adhesive
Steps
1. Place the instrument on a stable table and adjust it to a horizontal state through the front level.
2. According to the estimated viscosity value, select the appropriate rotor and speed combination through the automatic scanning function or manually.
3. Install the selected rotor to the instrument connector.
4. Pour the sample into a measurement cup with a capacity of 300~ 400ml.
5. Slowly immerse the rotor in the sample to the specified marking line.
6. Start the measurement program on the touch screen, the instrument starts swirling/spinning and measurement.
7. After the measurement is completed, the screen displays the viscosity value and related parameters (such as temperature, shear rate, etc.).
8. You can choose to save the measurement data (up to 30 sets) or print the data with Linear dispersion through the printer interface.
Notice
• Be sure to place the instrument horizontally before use to ensure measurement accuracy.
• Select the appropriate rotor and speed combination according to the estimated viscosity range of the sample to avoid range overflow.
• When installing and disassembling the rotor, the action should be gentle to avoid bending or damaging the rotor shaft.
• Ensure that the rotor is fully immersed in the sample to the specified marking line, and that the rotor should not touch the cup wall or bottom.
• After measurement of high viscosity samples, the rotor should be thoroughly cleaned to prevent residues from affecting subsequent measurements.
• The working voltage of the instrument supports a wide voltage (110V/60Hz or 220V/50Hz), please confirm that the local voltage matches.
• For kinematic viscosity measurement, enter the exact density value of the sample into the instrument.
• Optional temperature probe, Thermostatic bath and other accessories need to be properly connected and used to achieve accurate measurement under temperature control.
