• ✔【Working Principle】A synchronous motor rotates at a constant speed, connecting to a dial via a helical spring and a rotating shaft, thereby driving the rotor to spin. Due to the viscous drag effect of the liquid, the rotor experiences a torque directly proportional to the liquid's viscosity; this torque is detected and processed by a sensor, then converted into a viscosity value which is displayed on the screen.
• ✔【Digital Display & Intelligent Control】The viscometer features an intuitive LED digital display that clearly presents all key parameters, including rotor model, rotational speed, real-time viscosity, temperature, and torque percentage. Thanks to its sensitive touchscreen design, parameter configuration and data retrieval are remarkably simple, offering flexible and fluid oper-ation that significantly enhances both user experience and work efficiency.
• ✔【Multiple Rotor Configurations】The viscometer comes equipped with four rotors, covering a wide range of viscosity measurements. With its high-quality lifting system and angle adjustment mechanism, users can utilize adjustment knobs to set the optimal measurement height and position; furthermore, the integrated bubble level and leveling screws ensure the instrument remains perfectly horizontal, effectively minimizing measurement errors.
• ✔【High-Precision Measurement】This viscometer delivers reliable viscosity measurement data for Newtonian fluids, boasting an accuracy of up to ±3%. The instrument features a built-in high-performance torque sensor and a robust spindle system, ensuring precise viscosity testing for a wide variety of fluids in both laboratory research and industrial production control settings.
• ✔【Wide Range of Applications】The viscometer is primarily used to measure the absolute viscosity of Newtonian fluids and the apparent viscosity of non-Newtonian fluids. Its application scope covers a diverse array of substances, including inks, coatings, adhesives, greases, fruit juices, dairy products, cosmetics, pharmaceutical preparations, biological fluids, rubber compounds, slurries, and paper pulp.
