Overview
The SNB-1A-1T rotational viscometer is a modern viscosity measurement instrument integrated with touch screen technology. It adopts a 5-inch 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. It has the advantages of many measurement parameters, high accuracy, stable speed and strong anti-interference. It can replace imported instruments of the same type.
Features
1. Adopt ARM technology, built-in Linux system, simple operation interface, support self-built 30 sets of test procedures, convenient and fast viscosity testing and data analytics.
2. Precision measurement, each range are computer Automatic calibration, small error.
3. The display content is rich, can display viscosity, temperature, shear rate, shear stress, measurement value percentage (graphic display), range alarm, automatic scan results, current Measurement range, date, time, etc., and can enter the density to display kinematic viscosity.
4. Fully functional, supports timing measurement, access to 30 sets of measurement data, real-time display of viscosity Linear dispersion, print data and Linear dispersion.
5. Front level, easy to adjust the level intuitively.
6. Optional temperature probe, constant temperature bath, thermostatic cup, printer, standard viscosity sample and other accessories.
7. Support Chinese and English operating systems.
Principle
The rotational viscometer determines the viscosity of the liquid by driving the rotor to swirl/spin in the sample and measuring the Tack resistance to the rotor. For newtonian fluids, absolute viscosity is measured; for non-newtonian fluids, apparent viscosity is measured. The instrument displays parameters and Linedispersion visually on the touch screen through the built-in program Automatic calibration and calculation, combined with real-time Sensor data.
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 of the sample, select the appropriate rotor and speed combination through the automatic scanning function of the instrument or manually.
3. Install the selected rotor and inject the sample into the sample cup to the specified scale (capacity about 15-25ml).
4. Select or create a test program on the touchscreen and set measurement parameters (such as timing, temperature probe connection, etc.).
5. Lower the rotor to immerse the sample to the specified mark.
6. Start the measurement, the instrument will automatically run and display viscosity, temperature, Linear dispersion and other data in real time.
7. After the measurement is completed, the data can be saved (up to 30 groups), or the printer output data can be connected with Linear dispersion through the print interface.
8. Raise the rotor and clean the rotor and sample cup.
Notice
Make sure that the instrument has been adjusted to level before use to ensure measurement accuracy.
• Choose the rotor and rotational speed combination correctly according to the sample characteristics (e.g. estimated viscosity, whether it is newtonian fluid).
• The amount of injected sample must meet the regulations to ensure that the rotor immersion depth is correct.
• Avoid vibration or interference in the measurement process.
• Be careful when cleaning the rotor and sample cup to avoid damaging the rotor or affecting its accuracy.
• For accurate temperature control measurement, please select and use the corresponding thermostatic accessories (such as constant temperature bath, thermostatic cup).
• When saving data, note that the upper limit of instrument storage is 30 sets.
When connecting external devices (e.g. printers, temperature probes), make sure that compatible options are selected and connected correctly.
