5. Front level, level adjustment is intuitive and convenient.
6. Optional temperature probe, Viscometer special constant temperature bath, thermostatic cup, printer, standard viscosity sample and other accessories.
7. Support Chinese and English operating systems.
Principle
The rotational viscometer calculates the viscosity of the liquid by measuring the torque of the fluid against the rotor by driving a specific rotor at a set speed swirl/spin in the sample. For non-Newtonian liquids, the apparent viscosity is measured.
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 level 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 or manually.
3. Install the selected rotor and inject the sample into the sample cup to the specified scale (15-25ml).
4. Select or create a test program on the touchscreen and set relevant parameters (such as timing, density, etc.).
5. Lower the rotor to immerse the sample to a specified depth and initiate measurement.
6. The instrument displays viscosity, temperature, Linear dispersion and other data in real time, and the results can be saved or printed after the measurement is completed.
Notice
• Make sure the instrument is placed horizontally before use.
• Choose the rotor correctly based on sample characteristics (e.g. transparency, particulate matter (PM)) and estimated viscosity range.
• The amount of injected sample should be within the specified capacity (15-25ml) and ensure that the rotor immersion depth meets the requirements.
• When measuring non-newtonian fluids, the result is apparent viscosity, so be careful when interpreting the data.
• The instrument has wide voltage adaptability, but it is still necessary to confirm that the local Power supply voltage matches the instrument requirements.
• For accurate temperature control measurement, please select and use the corresponding thermostatic accessories.
Periodically calibrate instruments using standard viscosity samples such as standard silicone oil to ensure measurement accuracy.
When saving data, pay attention to storage space limitations (up to 30 sets).
